In order for linking the static libraries from elfutils to work,
other libraries need to be included to handle the references
to functions made in the library's objects that are not included
as they would already be if the library was a shared object instead.
A shared object library stores this list of libraries when it was made,
so that the dynamic linker can refer to that list at runtime,
but a static library has no such functionality so the list of libraries
for missing functions must be included at link time.
This information was already added to the pc file for libelf
using the definitions in src/Makefile.am,
so extend this to the rest of the pc files in the project.
For situations where the libraries may be used
without pkg-config setting the flags and library list,
this patch and the pc files can serve as a quick reference.

The use of ar to list the archive members in a library
in order to include them in another library is not portable.
On BSD and macOS, ar will also list
the special archive member "__.SYMDEF"
which is not a compiled object, rather it is
part of the metadata prepended to the library by ranlib.
Fix this by writing the list of unique objects used
to create the library into a separate "manifest" file
when the library is created, which will be read later
when the Makefiles of other subdirectories are ran.
Extend this to all other libraries whether or not they are linked
to another library for a shared object that is installed
so that it is possible for any of the libraries
to be statically built with more objects.
The use of the wildcard function to ignore the
special archive members which are only metadata
is no longer needed to prevent build errors.
Not using the wildcard function is preferred,
since errors should be caught during the build
instead of when linking something else or at runtime.

Importing gnulib in order to have a local portable library
to link against for missing functions currently requires
using libtool to produce the libgnu.la library.
Ideally, linking would be simple if the rest of the libraries
built by elfutils were also built using libtool, as linking
them together would not require any manipulations of library paths.
However, upstream elfutils does not support building the libraries
statically with libtool, so using libtool comes at the cost
of creating a huge patch to introduce that functionality.
For building on macOS, it turns out that libgnu.la is only needed
for building the binaries, and that just one or two objects from libgnu
are needed to build the libraries, so in this case, it would be simple
to add the specific non-libtool-wrapped library and objects
to the link paths as needed, rather than use libtool to link
the libtool wrappers, which greatly reduces the need to patch.
Not using libtool also makes the original Makefile definitions for LIBADD
once again be the right ones to use. However, to be portable,
for libdw the wildcard function needs to be used in order to exclude
special archive members like "__.SYMDEF" which are not compiled objects
because some BSD-like versions of ar include that metadata in the list,
or because the library included may have objects from another subdirectory.
Also, the rest of the subdirectories have custom "LDLIBS" variables
meant for building shared objects only, so define the LIBADD variables
with objects from those existing definitions so that when building only
the static versions of the libraries, those objects can still be included.

Overriding variables used in both the macros and the headers
like setting REPLACE_FCNTL to 0 while invoking Make causes the
function aliases like rpl_fcntl() to not be defined,
however the object may still be built with the fnctl() function.
Usually this is enough for building while avoiding
the need to link the resulting libgnu library
to every single other build target for a project
in order to include the gnulib copy of the function,
because in these cases we don't care which version
of the function is used.
However for functions like fcntl() this doesn't work
as it is designed to use either the alias or standard declaration
from gnulib headers in order to be
a wrapper for the native host copy of fcntl()
by containing recursive calls to fcntl() within itself
after undefining the gnulib function declaration.
Overriding the variables used by the header when invoking Make
causes the header's declarations to be blocked,
and this results in the gnulib version of fcntl()
to call itself recursively and indefinitely
leading to segmentation faults.
Fix this by using macros defined with those variables
in order to exclude the function during preprocessing.
While at it, do the same for reallocarray()
so that the configure option --avoid=reallocarray
and Make variable REPLACE_REALLOCARRAY set to 0
would have a similar effect.
In the future this patch can be expanded to include
more functions and some version of this may be upstreamable.

Since the Yafut tool is now used for both updating the kernel on

the tree as it is no longer used for anything.

The Yafut tool now has limited capabilities for working on filesystem
images stored in regular files. This enables preparing Yaffs2 images
for devices with NOR flash using upstream Yaffs2 filesystem code instead
of the custom kernel2minor tool.
Since minimizing the size of the resulting filesystem image size is
important and upstream Yaffs2 code requires two allocator reserve blocks
to be available when writing a file to the filesystem, a trick is
employed while preparing an OpenWRT image: the blank filesystem image
that Yafut operates on initially contains two extra erase blocks that
are chopped off after the kernel file is written. This is safe to do
because Yaffs2 has a true log structure and therefore only ever writes
sequentially (and the size of the kernel file is known beforehand).
While the two extra erase blocks are necessary for writes, Yaffs2 code
seems to be perfectly capable of reading back files from a "truncated"
filesystem that does not contain these extra erase blocks.
In terms of image size, this new approach is only marginally worse than
the current kernel2minor-based one: specifically, upstream Yaffs2 code
needs to write three object headers (each of which takes up an entire
data chunk) when the kernel file is written to the filesystem:
- an object header for the kernel file when it is created,
- an object header for the root directory when the kernel file is
created,
- an updated object header for the kernel file when the latter is
fully written (so that its new size can be recorded).
kernel2minor only writes two of these headers, which is the absolute
minimum required for reading the file back. This means that the
Yafut-based approach causes firmware images to be at most one erase
block (64 kB) larger than those created using kernel2minor, but only in
the very unfortunate scenario where the size of the kernel file is
really close to a multiple of the erase block size.
The rest of the calculations performed when the empty filesystem image
is first prepared stems from the Yaffs2 layout used by MikroTik NOR
devices: each 65,536-byte erase block contains 63 chunks, each of which
consists of 1024 bytes of data followed by 16-byte Yaffs tags without
ECC data; each such group of 63 chunks is then followed by 16 bytes of
padding, which translates to "-C 1040 -B 64k -E" in the Yafut
invocation. Yaffs2 checkpoints and summaries are disabled (using
Yafut's -P and -S switches, respectively) as they are merely performance
optimizations that require extra storage space. The -L and -M switches
are used to force little-endian or big-endian byte order (respectively)
in the resulting filesystem image, no matter what byte order the build
host uses. The tr invocation is used to ensure that the filesystem
image is initialized with 0xFF bytes (which are an indicator of unused
space for Yaffs2 code).

NAND flash via MTD character devices. Recent upstream updates extended
the tool with limited support for working with filesystem images stored

filesystem image for a device with NOR flash on a build host and
subsequently flashing it to the target device without using Yafut
itself.

The compiled library resulting from importing gnulib has been
linked to libelf in order to easily cover other link dependencies.
However, this is not appropriate for linking libelf to other programs
as it bloats the resulting libelf library, and may result in
multiple defintions of symbols based on whether or not
certain modules from gnulib are included while elfutils
already has it's own definition of a function.
This is not a problem while building elfutils, because gnulib has
it's own way of creating function aliases and special declarations
that allow the linker to ignore the original function definitions,
however, when libelf is used to link to something else,
this results in an error at link time.
The gnulib manual recommended linking the libraries directly,
but those who have written it may not have considered how this
can affect the ability to link that library in other builds,
they likely assume the build targets would not be a dependency.
Fix this by removing the linking between gnulib and libelf
and instead overriding Make variables in order to add linking
between gnulib and each of the binaries provided by elfutils,
using Make functions to avoid applying it to other subdirectories.
The function tdestroy() would still be missing on macOS,
but the existence of the gnulib tsearch object having been built
is an indicator of whether or not it is needed
because it is only built conditionally by gnulib,
so include linking that object only when it exists.
Block the unnecessary replacement of some functions by gnulib
so that future linking with libelf doesn't require
the associated gnulib "rpl" prefixed functions.
These replacements are very strict in order to correct
minor bugs that don't have a real impact in almost all cases
or new standards requirements that are not yet in effect or used.

The gnulib fts header is meant to not be overwritten

This is fine if the built libgnu library is directly linked

On some macOS platforms, the use of __DARWIN_INODE64

Undefined symbols for architecture x86_64:
"_rpl_fts_close$INODE64", referenced from:

Create a local fts header for gnulib

An alternative and more upstream friendly fix would be
to rename fts_.h to fts.h and add the macOS-only
include guard to that file within it's own include guard,
but that would be a massive patch, so do this for now.

New:
- mold is now up to 10% faster when linking very large, debug
info-enabled executables such as Blender (~1.8 GiB) or Clang (~3.8
GiB), thanks to several improvements we've made to the string merging
algorithm. (53ebcd8, d714301, 40f6b17, c9faf3d)
- -z start-stop-visibility=hidden is now supported so that
linker-synthesized __start_<section-name> and __stop_<section-name>
symbols can be completely hidden from other ELF modules. Previously,
only -z start-stop-visibility=protected was supported. (99a5b15)
- -Bsymbolic-non-weak and -Bsymbolic-non-weak-functions options are now
supported for compatibility with LLVM lld. Just like lld, these options
control which symbols are exported as dynamic symbols.
-Bsymbolic-non-weak makes the linker to export only weak symbols,
whereas -Bsymbolic-non-weak-functions makes it to export only weak
function symbols. (7d17aa8)
Bug fixes and compatibility improvements:
- Previously, if a linker script contains a newline character in the
beginning four bytes of a file, it was not recognized as a linker
script by mold. Now, mold allows newlines at the beginning of a file.
(ea054cc)
- Under rare circumstances, the INPUT linker script command may have
found a different file than GNU ld would. Now, mold's behavior aligns
with GNU ld's. (163975d)
- Previously, the --repro option produced corrupted tar files. Now the
bug has been fixed. (32c4a09)
- mold generally guarantees that its output is reproducible, meaning that
if you run the linker with the exact same command line options and
input files, the output is guaranteed to be bit-for-bit identical to
the previous outputs. However, under rare circumstances, it might
produce different output due to a bug. It's reported that this
nondeterminism caused random crashes for some programs (#1247). This
bug has been fixed. (6463a7c)
- mold no longer sets the address of the .text section as the entry point
address if --entry option is not given, just like LLVM lld. (020b1a7)
- [RISC-V] __global_pointer$ symbol is now exported from executables as
required by the processor-specific ABI. (3df7c8e)
- [ARM32] --long-plt option is now recognized as known option by mold.
mold ignores the option, though, because the PLTs generated by our
linker is always long. (d432e98)

intentional and added to prevent duplicate basename definitions.
This also means that for macOS we dont need to do any additional header
inclusions as the new helper takes care of basename.
So, to fix the symbol conflict we can simply drop the <dirname.h> inclusion
and build from elfutils.
Tested on Fedora 40 as well as macOS 14.4.1.

Quilt refresh combined two sets of changes to the same file.
The switch from using libgen.h to dirname.h because of function poisoning
from gnulib's import of basename() was added as a new patch hunk instead
of an edit to the original one.
The original patch hunk was to fix build errors on an earlier version of
elfutils before the "dirname" module was being imported to fix further
build errors with the 0.191 version.

A false tdestroy() function was added in order to make elfutils build on
macOS again. A previous commit added declarations for a real version of
tdestroy() into gnulib, which is already imported, as well as the
preprocessor flags and the triggers for the Makefile.am conditional in
order to include the source to be built.

On macOS, stdlib.h in the standard include paths does not provide
reallocarray() while both elfutils and gnulib do, however they are
declared differently, leading to an error:
./system.h:101:1: error: static declaration of 'reallocarray' follows non-static declaration
reallocarray (void *ptr, size_t nmemb, size_t size)
A normal "configure && make" build cycle results in both declarations
being enabled as a result of both elfutils and gnulib having completely
separate configure checks where gnulib uses an internal placeholder symbol
HAVE_REALLOCARRAY, and elfutils uses a standard autoconf macro
HAVE_DECL_REALLOCARRAY.
Fix this by excluding the import of the reallocarray module which causes
gnulib checks in the configure stage to not even consider whether to
declare reallocarray later on, so the decision is only between the
standard include stdlib.h and the elfutils header.

Organize the Makefile lines involved in gnulib importing and its
workarounds. It improves readability and keeps git history organized.
