configure: On Mac OS X, always specify target architecture to the dev tools.
Fixes building on Snow Leopard. Mac OS X doesn't have a concept of one
bit-ness being "native". So, which architecture gets built is somewhat
arbitrary. On Snow Leopard, the tools have changed to default to building
64-bit, which causes us problems. So, just always be explicit.
