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.
Fixes#1733

fix conflict options when compiling multilibs on ARM based architecture.
"--with-arch", "--with-cpu", "--with-fpu", "--with-float", and
"--with-mode" should not be configured with "--with-multilib-list=list"
when configuring multilibs.

This allows us to include the component-to-package relation in the
generated kconfig files and make use of that information in the
show-config.sh script.

1. On SuperH, configuring GCC with explicit variant of the CPU
(like "sh4") limits the default set of multilibs to just that CPU
and requires --with-multilib-list to change. Allow for "unspecified"
variant, so that we can defer to GCC to determine the list.
2. Support toolchains with both endiannesses at the same time.
3. Add a SuperH/newlib sample
4. Add more flags processing for uClibc

Also:
- Move companion_* to comp_* to match the kconfig symbols
- Replace bootstrap with former gen-versions.sh
- Fold *.in.2 into their respective first parts; this moves common
options to the end - if it is undesirable, inclusion of *.in
can be moved where *.in.2 used to be (but that will also move
version selection after common options).
- Retire addToolVersion.sh (may later replace with a more
comprehensive script that tries to download the added tarballs,
copy the patches and try to apply them, and create a version.desc).

The configure error mentioned in the commits that disable
--with-arch/--with-tune when --with-cpu is specified is specific to ARM
builds. For other architectures, it makes sense (hey, it even makes
sense for ARM - read 'info gcc'! - it is just a shortcoming of ARM
build, apparently).
Thus, add an arch setting ARCH_EXCLUSIVE_WITH_CPU (currently, set only
for ARM) that will trigger current behavior. Permit combinations of
--with-arch/cpu/tune for other arches.

First, 'SUPPORT' should be spelled 'SUPPORTS'.
Second, 'SUPPORT_XXX' really means 'supports --with-xxx', so rename the
affected options accordingly. Update the affected archs to match the new
namings.

ARM compilers can be built for soft float (software only, floats in
core registers), hard float (uses floating point instructions, floats
in FPU registers), or the half-way house softfp (uses floating point
instructions, floats in core registers).

The latest kconfig stuff is more stringent when it comes to validating
the dependency of the symbols. It is no longer possible to have a symbol
depend on itself (such as our construct for arch/cc/libc/... was doing).
Fix our generated-file infrastructure to avoid these situations when the
new kconfig stuff will be merged (in a following changeset).

Even if the selected ARCH does not support different bitness (or we do
not support building with another bitness), still select the appropriate
bitness.
Add config option to build wtarget code with THUMB interworking.
This is used to build the C library as well as all other code
that runs on the target.
