weak alias test

Browse Source 
This adds the test I was using when testing 60d67dc8.

	* testsuite/ld-elfweak/alias.c,
	* testsuite/ld-elfweak/alias.dat,
	* testsuite/ld-elfweak/aliasmain.c,
	* testsuite/ld-elfweak/weakref1.c,
	* testsuite/ld-elfweak/weakref2.c: New test.
	* testsuite/ld-elfweak/elfweak.exp: Run it.  Don't return on fails,
	attempt other tests.
