Subject: Small PATCH to rs6000.c to fix cross-compiler build without gas

If configure doesn't think that the assembler supports weak symbols, 
rs6000.c fails to compile because ASM_WEAKEN_DECL isn't defined.  So 
let's not use it in that case.

OK for trunk?

    	* config/rs6000/rs6000.c (rs6000_code_end): Protect the use of
    	ASM_WEAKEN_DECL with #if RS6000_WEAK.
