osf.h (ASM_OUTPUT_WEAK_ALIAS, [...]): Define.

Browse Source 
* config/alpha/osf.h (ASM_OUTPUT_WEAK_ALIAS, ASM_WEAKEN_LABEL,
	HANDLE_SYSV_PRAGMA): Define.
	* mips-tfile.c (add_ext_symbol): Pass complete symbol ptr, inline
	previous args.
	(copy_object): Caller changed.

	testsuite:
	* g++.old-deja/g++.pt/static3.C: Removed alpha*-*-osf* XFAIL.
	g++.old-deja/g++.pt/static6.C: Likewise.
	* lib/target-supports.exp (check_weak_available): alpha*-*-osf*
	supports weak symbols.
