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.

I also run into this. The bug is in rs6000.h:
#ifdef HAVE_GAS_WEAK
#define RS6000_WEAK 1
#else
#define RS6000_WEAK 0
#endif
#if RS6000_WEAK
/* Used in lieu of ASM_WEAKEN_LABEL. */
#define ASM_WEAKEN_DECL(FILE, DECL, NAME, VAL) \
do \
{ \
fputs ("\t.weak\t", (FILE)); \
RS6000_OUTPUT_BASENAME ((FILE), (NAME)); \
if ((DECL) && TREE_CODE (DECL) == FUNCTION_DECL \
&& DEFAULT_ABI == ABI_AIX && DOT_SYMBOLS) \
{ \
if (TARGET_XCOFF)
..
ASM_WEAKEN_DECL is used unconditionally.

The ASM_WEAKEN_DECL use in rs6000.c is now conditional.
