tell dejagnu that darwin has weak


Since my last patch made GCC not use weak symbols in the bootstrap
(just in the libstdc++ build), I went looking for a good place to put
a testcase.  I found one.  I also found many tests that could be being
run, if only dejagnu was a bit smarter...

Tested with 'make check-gcc'.

	* gcc.dg/weak/typeof-2.c: Needs aliases as well as weak.
	* gcc.dg/weak/weak-3.c: Likewise.
	* gcc.dg/weak/weak-5.c: Likewise.
	* gcc.dg/weak/weak-9.c: Likewise.
	* lib/file-format.exp (gcc_target_object_format): Darwin has Mach-O.
	* lib/target-supports.exp (check_weak_available): Mach-O does weak.
