Properly check linker option in LIBC_LINKER_FEATURE [BZ #28738]
Update LIBC_LINKER_FEATURE to also check linker warning message since unknown linker -z option may be ignored by linker: $ touch x.c $ gcc -shared -Wl,-z,foobar x.c /usr/bin/ld: warning: -z foobar ignored $ echo $? 0 $ This fixes BZ #28738. Reviewed-by: Florian Weimer <fweimer@redhat.com>
