re PR libgomp/38086 (libgomp fails to build if assembler doesn't support .symver)
PR libgomp/38086
* acinclude.m4 (HAVE_AS_SYMVER_DIRECTIVE): New check.
* libgomp.h (LIBGOMP_GNU_SYMBOL_VERSIONING): Undefine if
HAVE_AS_SYMVER_DIRECTIVE is not defined.
* configure: Regenerated.
* config.h.in: Likewise.
