- Remove upstreamed patch 0001. Patches to localedef are not upstream.
- allow to use optimization CFLAGS (not CPPFLAGS) which are nowadays
supported by upstream (except nios2)
- enable support for or1k, which is now included upstream
- runtime tested with qemu-system for aarch64/arm/microblaze/mips/mips64/nios2/
or1k/powerpc/powerpc64/powerpc64le/riscv32/riscv64/s390x/sh4/sparc64/x86/x86_64
Since only a single version is supported (no csky fork any more), move
the hash file out of the version directory. Also, make a symlink from
the localedef to the glibc hash file rather than copying it.

This reverts commit 8e91385a2c.
This commit is incorrect, as it is perfectly valid for
BR2_TOOLCHAIN_EXTERNAL_PATH to be empty. The help text of
BR2_TOOLCHAIN_EXTERNAL_PATH even documents it as a supported case:
If empty, the compiler will be searched in $PATH.
Commit 392b0a26f5 ("toolchain-external:
default BR2_TOOLCHAIN_EXTERNAL_PATH to empty") even made that the
default saying "In addition, it in fact works correctly when it is
empty. In that case, the toolchain will be searched in PATH."

Until commit "arch/Config.in.sh: fixup MMU selection" in this series,
SH2A could either be used with BR2_USE_MMU disabled or BR2_USE_MMU
enabled.
The later made absolutely no sense, since SH2A does not have a MMU:
MMU support was introduced starting from SH3 according to
https://en.wikipedia.org/wiki/SuperH#SH-3
Also, since commit 22d5501e03 ("arch:
tidy up binary formats config"), which was merged in Buildroot
2015.05, the architecture tuple used when BR2_sh2a=y and BR2_USE_MMU
disabled is sh2a-buildroot-uclinux-uclibc, and this was already
unsupported back in the days of Buildroot 2015.08 and binutils 2.24,
causing the build to fail with:
*** BFD does not support target sh2a-buildroot-uclinux-uclibc.
just like it fails to build today with recent version of binutils.
So, this has been broken since 2015.08, and nobody complained. SH2A is
seldom used, so it's time to kill it.
It is worth mentioning that there had been an attempt at resurrecting
SH2 support around 2015 (see https://lwn.net/Articles/647636/) as part
of the J2 core. This effort led to the addition of FDPIC support for
SH2A in the musl C library (and therefore proper ELF binaries, with
shared libraries), but that was never supported in Buildroot. Now that
the J2 project is essentially dead, there is no reason to bother with
this.

Convert BR2_TOOLCHAIN_EXTERNAL_PATH to an absolute path when used.
Otherwise the symbolic links to the external toolchain binaries are
not installed in host/bin when BR2_TOOLCHAIN_EXTERNAL_PATH is relative.
This happens because TOOLCHAIN_EXTERNAL_INSTALL_WRAPPER
changes directory into host/bin to create the symbolic links.
From there the tools are no longer found via the relative path and
a single symbolic link host/bin/$(prefix)-* is created instead.
Although relative paths sounds like something less than ideal to put in
a Buildroot configuration, it's actually rather typical to put the
buildroot sources as a submodule (or subdirectory) of custom sources
(either in a BR2_EXTERNAL or not), in which case the relative path is
well-defined.

In GCC6 the compiler was made smarter to omit the flag
-fdebug-prefix-map from the DWARF DW_AT_producer section[1]. That flag
contains the absolute path '$(BASE_DIR)' which breaks reproducibility.
Prior to GCC6 however, the only way to omit the flag is to use
-gno-record-gcc-switches which omits all flags.

handling the __FILE__ macros, but not debug info paths. Use
-fdebug-prefix-map to clean them up. This option exists since GCC 4.3.0,
which is our minimal supported GCC version.

The gdbinit supplied by Buildroot does two things:
A. specify the sysroot where gdb can find shared libraries
B. mark the sysroot as a 'safe path' for its auto-load feature, to make sure
that pretty printers for libstdc++.so are added automatically (see commit
6fb3216a80)
When debugging a core file, and the gdbinit file is specified via '-x'
rather than '-ix', then the order of these settings matters: If you first
set the sysroot, then gdb will immediately start finding the shared
libraries it needs for the core file, detect libstdc++ and its associated
libstdc++-gdb.py file, then give a big warning about safe paths:
warning: File ".../i686-buildroot-linux-gnu/sysroot/lib/libstdc++.so.6.0.24-gdb.py"
auto-loading has been declined by your `auto-load safe-path' set
to "$debugdir:$datadir/auto-load".
To enable execution of this file add
add-auto-load-safe-path .../i686-buildroot-linux-gnu/sysroot/lib/libstdc++.so.6.0.24-gdb.py
line to your configuration file "/home/me/.gdbinit".
To completely disable this security protection add
set auto-load safe-path /
line to your configuration file "/home/me/.gdbinit".
For more information about this security protection see the
"Auto-loading safe path" section in the GDB manual. E.g., run from the shell:
info "(gdb)Auto-loading safe path"
and the pretty printing code is not loaded. This is because the second
line from the gdbinit file was not yet parsed at this point.
By changing the order (first configuring the safe path, then setting the
sysroot), this issue does not appear and everything is as expected.
Note that when '-ix' were used instead of '-x' to pass the gdbinit file to
gdb, then the order would not matter, because the entire gdbinit file would
be parsed before considering the core file.
However, even though the Buildroot manual now suggests '-ix', users may not
have noticed this change and continue to use '-x'.

gdb can automatically load certain files as described in [1]. Such files
could install pretty-printers for complex data structures.
libstdcxx (C++ standard library) provided by gcc, is one example of a
library for which such auto-load file is available. But there are other
examples too, like libglib2.
However, gdb will only auto-load files if the file is located in one of the
locations treated as 'safe'. The Buildroot sysroot is not by default in that
list.
Provide a better debugging experience by adding the sysroot to the 'safe'
list, via the gdbinit file prepared by Buildroot.

gcc installs a libstdcxx-...so-gdb.py file that gdb will load automatically
when it loads libstdcxx.so, via the mechanism described at [1].
However, the auto-load file installed by gcc contains hardcoded paths
referring to the location where the (external) toolchain was built, which
are normally not available.
Fix up the paths in the load file so that the pretty printers can be loaded
automatically.
Note that gdb will only auto-load the file if its location is marked as
'safe'. A subsequent commit will take care of that.
Technically, there could be more than one load file, e.g. in lib and
usr/lib, so fix them all. This was for example observed in
BR2_TOOLCHAIN_EXTERNAL_ARM_AARCH64.
In a very specific case with a local custom toolchain, there were actually
two 'python' directories, which would break the sed command, so arbitrarily
limit to the first one encountered.
