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.

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.

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).

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.
