remove -gz=zlib-gnu option value
The option value is legacy and probably not used at all,
thus ignore it.
gcc/ChangeLog:
* configure: Regenerate.
* configure.ac: Simplify to gcc_cv_ld_compress_debug={0,1}
and gcc_cv_as_compress_debug={0,1}.
* doc/invoke.texi: Document the removal.
* gcc.cc (LINK_COMPRESS_DEBUG_SPEC): Simplify and ignore
zlib-gnu.
(ASM_COMPRESS_DEBUG_SPEC): Likewise.
