    libsanitizer: Check assembler support for symbol assignment [PR112563]

    The recent libsanitizer import broke the build on Solaris/SPARC with the
    native as:

    /usr/ccs/bin/as: ".libs/sanitizer_errno.s", line 4247: error: symbol
    "__sanitizer_internal_memset" is used but not defined
    /usr/ccs/bin/as: ".libs/sanitizer_errno.s", line 4247: error: symbol
    "__sanitizer_internal_memcpy" is used but not defined
    /usr/ccs/bin/as: ".libs/sanitizer_errno.s", line 4247: error: symbol
    "__sanitizer_internal_memmove" is used but not defined

    Since none of the alternatives considered in the PR worked out, this
    patch checks if the assembler does support symbol assignment, disabling
    the code otherwise.  This returns the code to the way it was up to LLVM=
 16.

    Bootstrapped without regressions on sparc-sun-solaris2.11 (as and gas) =
and
    i386-pc-solaris2.11 (as and gas).
