If the configure scripts think the cross assembler does not support .weak
symbols, the compiler will fail because it does not define ASM_WEAKEN_DECL. 
Note, when I tried this on August 16th, 2012, the current head of binutils
seems broken (the archiver segfaults), but the 2_21 branch builds it fine on my
Linux system with a target of powerpc64-linux and additional targets of
powerpc-linux.  Obviously the compiler should do something more appropriate if
the assembler does not support .weak symbols.
