[testsuite] Mark tests unsupported when relocation truncation occurs on tiny memory targets

* lib/gcc-defs.exp (${tool}_check_unsupported_p):
	Return memory full when we have a tiny target and relocation
	truncation occurs.
	* lib/gcc-dg.exp (gcc-dg-prune): Likewise.
	* lib/objc.exp (${tool}_check_unsupported_p): Likewise.
	* lib/target-supports.exp (check_effective_target_tiny): New function.
