356b7e47c9 Use 2-stage bootstrap 
Apparently GCC 12 needs proper glibc for all-target-libgcc.
In particular libatomic fails to build due to missing/incorrect
definition of MB_LEN_MAX:

Therefore use the (slow) 2 stage bootstrap, i.e. build C-only
toolchain without libc, and use that one to cross-compile
the complete target glibc.

7c1209626a .gear/rules: change specsubst variable for local build 
To build locally one need to specify the variable in .git/config.
However a git variable name must not contain `_` character.
Use @targetarch@ in specsubst to avoid the problem

b993013466 Avoid build failure due to inappropriate checks 
Recently yet another post-build check has been added:

/usr/bin/strip: Unable to recognise the format of the input file `./usr/lib/aarch64-linux-gnu/sys-root/usr/lib64/libc.a(getutxid.o)'

which (unsurpisingly) broke the build.
Tell strip to ignore the foreign libraries.

Avoid hard-coding versions of {gcc,binutils,glibc}-sources so there's no
need to updated the spec whenever GCC, binutils, or glibc gets rebuilt.

dfe065bd30 altcross.sh: disable libsanitizer to avoid build error 
libsanitizer wants limits.h, which is a part of compiler. However
the compiler hasn't been installed yet, since we are building its
runtime. Disable libsanitizer to avoid the problem.

TODO: Perhaps there's a special target to build an install compiler
headers only. Figure it out and re-enable libsanitizer.

39afecc492 driver: run ${target}-as as a last resort 
As of now the driver tries to locate `as` (and `ld`) somethere in $PATH
if nothing was found in libsubdir and tooldir. This is a bad idea for
a cross-compiler. Use DEFAULT_TARGET_MACHINE-{as,ld} instead.

Note that `collect2` already behaves that way (which is a good thing).

3e238594dd Added as, ar, ld, etc symlinks into /usr/libexec/gcc/aarch64-linux-gnu/8 
Apparently `invoke_as:` directive in GCC spec file applies to running
assembler on C/C++ compiler output. However compiling `assemble` (.s) and
`assembler-with-cpp` pseudo-languages use `as`  instead of ${target}-as)
anyway. Fortunately GCC searches for `as` in libexec/gcc/$target/$version
directory. Therefore add symlink to ${target}-as into that directory.
Do the same thing for ar, ld, nm, objcopy, etc just in a case.

bd427575f9 Build on x86_64 only 
aarch64-targeted cross-compiler definitely does not make any sense on
aarch64 and armh (native or multilib compilers are available).
Using 32-bit x86 as a development platform does not make any sense either.
Same applies to mipsel. ppc64el and e2k might be powerful enough but
these machines are way too rare/expensive.
