Backport an upstream patch series that adds backend elfutils support for
DWARF relocations in MIPS debug info. This support is needed by pahole to
generate BTF for modules in BTF-enabled kernel builds.
The problem first manifests as pahole warnings during build:
BTF [M] lib/libcrc32c.ko
die__process_unit: DW_TAG_compile_unit (0x11) @ <0x932d> not handled!
die__process_unit: tag not supported 0x11 (compile_unit)!

die__process_unit: tag not supported 0x11 (compile_unit)!
die__process: got compile_unit unexpected tag after DW_TAG_compile_unit!
During system boot the problem then causes module loading failures, which
may result in many other runtime issues:

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

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).

The Yafut tool has so far been used to update the kernel on devices with
NAND flash via MTD character devices. Recent upstream updates extended
the tool with limited support for working with filesystem images stored
in regular files. This enables Yafut to be used for preparing a Yaffs
filesystem image for a device with NOR flash on a build host and
subsequently flashing it to the target device without using Yafut
itself.
Add Yafut to tools/ so that it can be compiled and run on the host

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.

Install binaries that are not common with binutils
instead of none at all. This adds a negligible time to the build.
Building shared libraries is disabled, so the AM_LDFLAGS can be reset
without the rpath-link option which is unrecognized by clang.
Some of the binaries depend on functions that are defined
using a "strong alias" instead of a normal definition,
but this is disabled by our patches in order to work on macOS,
so use the identical function directly instead.
Add fnmatch from gnulib with GNU extensions
which is needed for usage of the FNM_EXTMATCH flag.
Handle a "Wunused-const-variable" error with the same

The gnulib fts header is meant to not be overwritten
in any way by the host system's copy of fts.h
and was therefore given a unique name instead.
This is fine if the built libgnu library is directly linked
with the target library, but if we want to keep them isolated
we end up having the definitions being mangled anyway
when the next object to link against included the fts.h header.
On some macOS platforms, the use of __DARWIN_INODE64
is messing with the link name for fts functions, resulting in:
Undefined symbols for architecture x86_64:
"_rpl_fts_close$INODE64", referenced from:
...
Create a local fts header for gnulib
that completely blocks the macOS host fts header.
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)

In the 0.191 update dirname was used instead of <libgen.h> to fix the
poisoned basename error:
/usr/include/libgen.h:35:9: error: attempt to use poisoned "basename"
35 | #define basename __xpg_basename
However, doing this has lead to libelf.a pulling in xmalloc, xstrdup and
friends and statically linking them thus leading to a symbol name conflict
with FRR host build and anything else that links against libelf and uses
xmalloc and friends.
Well, it turns out that upstream has added a helper[1] for basename so it
can compile with musl 1.2.5 which dropped the basename declaration, but it
also means that we must NOT include <libgen.h> and that poisoned error is
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.

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.

This patch is large but upstreamable, including all of the macros and

portable support, like using the @@ placeholder/substitution method to
determine whether or not to have declarations based on whether or not
tdestroy() is already declared within the standard headers of the default

fix for it.

Changes:
* Improved CRC-32 performance on recent x86 CPUs by adding
VPCLMULQDQ-accelerated implementations using 256-bit and 512-bit vectors.
* Improved Adler-32 performance on recent x86 CPUs by adding
VNNI-accelerated implementations using 256-bit and 512-bit vectors.
* Improved CRC-32 and Adler-32 performance on short inputs.
* Optimized the portable implementation of Adler-32.
* Added some basic optimizations for RISC-V.
* Dropped support for gcc versions older than v4.9 (released in 2014) and
clang versions older than v3.9 (released in 2016).
* Dropped support for CRC-32 acceleration on 32-bit ARM using the ARMv8 pmull or crc32 instructions.
This code only worked on CPUs that also have a 64-bit mode, and it was
already disabled on many compiler versions due to compiler limitations.
CRC-32 acceleration remains fully supported on 64-bit ARM.

Now that instead of relying on env variables for the GH download script
invoking ZSTD tarball compression it passes the full arguments via tar -I
we can drop the CLI max compression level override.

The current .pc generated by make build system for zstd is wrong and
always assume a single-threaded library is used.
This wasn't the case for the meson build system that used his own logic
to generate the pkg-config file.
Add a patch to fix this by introducing install-mt-pc make target to
generate the correct pkg-config gile.
