Hello you want these flags pretended to your waf configure command:

CFLAGS="-arch i386 -arch x86_64" LDFLAGS="-arch i386 -arch x86_64" ./waf configure ......

This will give you a universal binary compatible with 32bit and 64 bit hosts. If you want 32bit only just remove the appropriate -arch flags.
