glibc versions prior to 2.23 don't compile successfully with
--enable-default-pie. While it would be nice to automatically prevent
this from being selectable the simplest thing is to update the sample
configs that use the older glibc versions to avoid the problem.

PIE is not supported by PRU and AVR backends for GCC.
This fixes LD errors when trying to link user programs with a
crosstool-NG toolchain:
/home/dinux/x-tools/avr/lib/gcc/avr/12.2.0/../../../../avr/bin/ld: -pie not supported

${CT_PREFIX_DIR} may contain relative paths (e.g.
"${CT_TOP_DIR}/../x-tools/${CT_TARGET}"). Code added in commit d83a0036
("Add symlinks from the libraries' original location to the new one.")
didn't cope well with this. As we're already calculating
${cannon_prefix} make use of it when adding the symlinks. This avoids
any issues with ${CT_PREFIX_DIR}.

This warning is designed to catch likely vulnerabilities in code run
under memory protection -- allowing execution from memory which is
writable. However, embedded arm systems frequently require placing code
in RAM, for performance or functionality reasons. Disable the warning
that recent versions of binutils has added.

Add sample config for target loongarch64-unknown-linux-gnu.
Currently, it fails to build on macOS due to flex/bison incompatibility.

This commit adds architecture support for LoongArch.
The toolchain currently only supports the 64-bit target
loongarch64-unknown-linux-gnu.
It has been tested to build with GCC 12.1, GDB 12.1, Glibc 2.36, Linux
5.19 and Binutils 2.39 as of Aug 2022.

Add binutils 2.39 and regenerate patches.
0008-binutils-2.38-vs.-ppc32-linux-kernel.patch is dropped as it has
been applied upstream. Add a milestone for 2.39 which will be handy for
Loongarch.
Binutils now requires bison >= 3.0.4 to build gprofng for x86/aarch64 so
we build our own bison when the host bison does not meet that
requirement (which appears to be the case on macOS).

libsanitizer is only supported on selected architectures. Add
ARCH_SUPPORTS_LIBSANITIZER and have architectures select this option
based on the list of supported configurations from GCC's
libsanitizer/configure.tgt. Support for mips64 was added in GCC12 so
this is an additional condition for the mips architecture.

This reverts commit 1b6ad7cd48. As it
turns out libsanitizer isn't supported on mips64 with GCC11 or older
(there is support in GCC12). The bug is actually the fact that ct-ng
allows configuring libsanitizer for architectures that don't support it.

After building the cross toolchain and compile a simple C program,
objdump reports debug information even though -g modifier was not

we want to add debug information to glibc, by default is enabled.

Make the requirement for bison harder (but not strict). The system bison
will be used to build kconf. If the system bison is not GNU bison 2.7 or
later crosstool-ng will build GNU bison as a companion tool if necessary
(for glibc 2.29 or newer).
