Yeah, it depends on how config.guess works
If it is not enough, do something like this

 CC="gcc -arch x86_64" ./configure --build=x86_64-apple-darwin`uname -r`

Darwin is a mess in that they use the same triplet for both 32-bit and 
64-bit.  It's probably possible to add a AC_CHECK_SIZEOF(long) in 
configure.ac, and use that to detect whether we're on 32- or 64-bit. 
Or, install both versions and dispatch based on some #define that the 
preprocessor defines by default... many possibilities.
