Thinking on this more, I suspect this is misguided attempt at emulating the
compiler wrappers in fink. Again the compilers wrappers in fink pass -m32 or
-m64 as shell script symlink for the actual compiler. This means that -m32
or -m64 are passed effectively on CC and *NOT* on any compiler flags like
CFLAGS, FFLAGS, or CXXFLAGS. Doing that will never allow the multilib to build
in gcc because you are short-circuiting it when it attempts to build -m32.
My guess anyway.

ps None of these build issues every existed on fink even before the compiler
wrappers when you pass the appropriate triplets.
