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
used. These debug segments are in glibc library and CRT files. So

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

Make the requirement for bison harder (but not strict). The system bison

For some reason GCC 12 ends up hitting the _MIPS_SIM_NABI32 case for
Linux's arch/mips/include/uapi/asm/stat.h when building libsanitizer.
This is basically the opposite of the problem from
