mbind gas tests and supports_gnu_osabi testsuite infrastructure
With the addition of section16 tests we have multiple tests advertising themselves as "mbind sections" and "mbind section contents". This patch fixes that, and fails on quite a few targets that force an OSABI value. It's a pain specifying all the relevant arm targets on an xfail line, so I wrote supports_gnu_osabi. binutils/ * testsuite/lib/binutils-common.exp (match_target): Accept '!' before TCL procedure. (supports_gnu_osabi): New procedure. (is_generic): New, from ld-lib.exp. (supports_gnu_unique): Use the above. gas/ * testsuite/gas/elf/section12a.d: Use supports_gnu_osabi in xfail, and rename test. * testsuite/gas/elf/section12b.d: Likewise. * testsuite/gas/elf/section16a.d: Likewise. * testsuite/gas/elf/section16b.d: Likewise. ld/ * testsuite/lib/ld-lib.exp (is_generic): Delete. * testsuite/ld-unique/unique.exp: Exclude tic6x.
