	* elflink.h (elf_link_add_object_symbols): Handle .symver x, x@FOO.
ld/testsuite/
	* ld-shared/shared.exp: Run on s390*-*-linux* and x86_64-*-linux* too.
	xfail tests linking non-pic code into shared libs on x86_64-*-linux*.
	* ld-elfvsb/elfvsb.exp: Likewise.
	* ld-elfvers/vers.exp: Likewise.  Add vers24a, vers24b and vers24c
	tests.
	* ld-elfvers/vers3.ver: Allow VERS_2.0 to come before GLIBC_*
	version.
	* ld-elfvers/vers19.ver: Likewise.
	* ld-elfvers/vers24a.c: New test.
	* ld-elfvers/vers24b.c: New test.
	* ld-elfvers/vers24c.c: New test.
	* ld-elfvers/vers24.map: New test.
	* ld-elfvers/vers24.rd: New test.
	* lib/ld-lib.exp (run_ld_link_tests): Add optional 7th argument
	cflags.  If source files have .c extension, compile them first.
