After much struggling with macos (BSD) sed and even getting everything
work in crosstool-ng itself, I had to abandon that because some
components rely on GNU syntax. Specifically, GNU libc uses '/.../{H;g}'
(note absense of the separator after 'g').
So, revert the -r/-E detection and check for sed's being of GNU origin.
MacOS people, sorry, but you'd have to install GNU sed.

... and then use the right option. See the note in scripts/functions
on where we should use ${foo} and where just 'foo'; this boils down to
whether we can expect the build tools override to be in effect (e.g. in
the actual build scripts) or not (i.e. outside of scripts/build).
While running in scripts/functions, or in scripts/crosstool-NG.sh the
build tools override directory (.build/tools/bin) may have not been
set up (yet, or at all).
Also, modify the installed scripts (populate, xldd) accordingly.

The referenced commit replaced 'make' with '${make}' everywhere. This is
wrong for at least the utilities that we may build as companion tools
(make, libtool): this will always invoke the version detected by configure
by supplying the absolute path. In other words, the wrappers in
.build/tools/bin are not fallbacks - they are either temporary (in case
a respective companion tool is built) or permanent redirectors.
This is the reason why the PATH= has .build/*/buildtools/bin at higher
precedence than .build/tools/bin; the latter has the versions detected by
configure and the former has the versions built as companion tools.
Revert the rest of the gang (grep/sed/...) for consistency. After all,
we may decide to supply some of them as well (awk, for instance).

This step was only used in uClibc. However, with upcoming multilib, the
config management will have to be done for each variant differently,
anyway.
uClibc was the only user of libc_check_config step, as well as
CT_CONFIG_DIR directory. Retire these.
Two other clean-ups in uClibc.sh:
- KERNEL_HEADERS check seems to be bogus, this config option is not
present even in 0.9.30 - which is not supported already.
- SHARED_LIB_LOADER_PREFIX was renamed to MULTILIB_DIR in 0.9.31,
according to ChangeLog - and MULTILIB_DIR is passed from command line
instead.

Install startfiles for libc variants into the most specific combination
(suffixed sysroot, if applicable + suffixed multi-os dir, if
applicable). Install headers once in every suffixed sysroot (although it
seems that GCC picks up headers from top-level sysroot, GCC manual
claims that sysroot suffix affects headers search path).
In uClibc, this requires a better sanitization of the directory: it
creates symlinks from {sysroot}/usr/lib/{multi_os_dir} to
{sysroot}/lib/{multi_os_dir} and to do so, it counts the number of path
components in the libdir. This breaks if one of such components is `..'
- symlinks contain an extra `../..' then. Since such sanitization had to
be implemented anyway, use it in other places to print more sensible
directory names.
Also, fix the description of configure --host/--target per musl's
configure help message (and its actual code).

On some arches (e.g. MIPS) the options like -mabi do not work if
specified more than once (see the comment in 100-gcc.sh). Therefore,
we need to determine which of the options produced by <arch>.sh can
be passed to multilib builds and which must be removed (i.e., which
options vary among the multilibs).
This presents a chicken-and-egg problem. GCC developers, in their
infinite wisdom, do not allow arbitrary multilib specification to be
supplied to GCC's configure. Instead, the target (and sometimes some
extra options) determine the set of multilibs - which may include
different CPUs, different ABIs, different endianness, different FPUs,
different floating-point ABIs, ... That is, we don't know which parts
vary until we build GCC and ask it.
So, the solution implemented here is:
- For multilib builds, start with empty CT_ARCH_TARGET_CFLAGS/LDFLAGS.
- For multilib builds, require core pass 1. Pass 1 does not build any
target binaries, so at that point, our target options have not been
used yet.
- Provide an API to modify the environment variables for the steps that
follow the current one.
- As a part of multilib-related housekeeping, determine the variable
part of multilibs and filter out these options; pass the rest into
CT_TARGET_CFLAGS/LDFLAGS.
This still does not handle extra dependencies between GCC options (like
-ma implying -mcpu=X -mtune=Y, etc.) but I feel that would complicate
matters too much. Let's leave this until there's a compelling case for
it.
Also, query GCC's sysroot suffix for targets that use it (SuperH,
for example) - the default multilib may not work if the command line
specifies the default option explicitly (%sysroot_suffix_spec is not
aware of multilib defaults).

The previous patch added the function 'CT_DoMultilibTarget()' to
scripts/build/arch/*.sh.
This patch calls the common function to (currently) get just the target
tuple for the current multilib target.
This patch was originally by: Cody P Schafer
Changed by Alexey Neyman: first, try `gcc -print-multiarch`. If it is
supported, use whatever it reports. Otherwise, fall back to our
guesswork. Move "i486" quirk into glibc.sh, as it is specific to glibc
(e.g. uclibc will need i386, which is what GCC reports).

The previous version of CT_GetCustom was a bit... funky.
It didn't handle custom versions to location very well.
This new version is exactly as it appears:
CT_GetCustom <name> <version> <location>
The name is the beginning of the archive (file or directory).
The version is the second half of the archive.
The location is where it can be found. This should be made an absolute
path, but this version is expecting the path in kconfig to be absolute.
A file should extract to a directory: <name>-<version>
A directory will be copied to: <name>-<version>
This keeps our expectations of what we should get.

This commit adds 4 new functions to aid in the process of managing a

* CT_KconfigSetOption <option> <value> <file>
* CT_KconfigEnableOption <option> <file>
* CT_KconfigDisableOption <option> <file>
* CT_KconfigDeleteOption <option> <file>
(akin to how buildroot manages the uClibc.config)
These functions are global so that we can manage any component that also
uses kconfig, or to be able to use it internally on Crosstool-NG's
kconfig files.
Last but not least, be consistent and update sed to be ${sed}!

Add support for applying arch-specific patches found in
"patches/${pkgname}/${version}/${CT_ARCH}".
This is needed for applying a popular binutils patch specific for the
AVR architecture but which isn't isolated for AVR in binutils' code.
In this case, applying it for every architecture would end up bloating
binutils' "size" options with AVR specifics.
This feels like a bit of a hack but it is easy enough to support with
current crosstool-ng infrastructure, seems like worth it for this case.

This commit adds support for the avr-libc C library.
According to the project page at http://www.nongnu.org/avr-libc , the
avr-libc package provides a subset of the standard C library for Atmel
AVR 8-bit RISC microcontrollers. In addition, the library provides the
basic startup code needed by most applications.
Support for this library in crosstool-ng is only enabled for the AVR
8-bit target.
The avr-libc manual and most distributions build the AVR 8-bit gcc
toolchain with the "avr" (non-canonical) target.
Some experimentation also led to the conclusion that other (canonical)
targets are not very well supported, so we force the "avr" target for
crosstool-ng as well.
The manual also recommends building avr-libc after the final gcc build.
To accomplish this with crosstool-ng, a new do_libc_post_cc step is
added, in which currently only avr-libc performs its build, and is a
no-op for the other libc options.
