re PR target/6077 ([alpha-osf].s with -x assembler-with-cpp breaks mips-tfile)

PR target/6077
	* gcc.c (input_suffix_matches): Tweak the semantics of %{.s:...}
	and %{.S:...} (and their negative variants) to test whether the
	input file is assembler or pre-processed-assembler independent of
	the actual filename extension.
