[PATCH v2] ld: Limit "readelf --got-contents" tests

[H.J. Lu]

Since "readelf --got-contents" tests use -melf_i386, -melf_x86_64 and
-melf32_x86_64 emulations, limit theses tests to targets with those
emulations.

	PR ld/33350
	* testsuite/ld-i386/binutils.exp: Limit tests to targets with
	-melf_i386 support.
	* testsuite/ld-x86-64/binutils.exp: Limit -melf_x86_64 tests to
	targets with -melf_x86_64 support and limit -melf32_x86_64 tests
	to targets with -melf32_x86_64 support.
