screwed this up, should be:

Then I compiled with architecture=x86 address-model=32_64 and got universal
binaries as I needed:

$ lipo -info lib/libboost_iostreams-xgcc42-mt-1_40.dylib
Architectures in the fat file: lib/libboost_iostreams-xgcc42-mt-1_40.dylib
are: i386 x86_64

I also tried architecture=combined address-model=32_64 (after I removed
-arch ppc64 from tools/darwin.jam), and confirmed that again, the "-m64" is
what causes errors (I tested that it somehow forces 64-bit even if you
previously specify 32-bit arch(s) with -arch option). With the same fix for
-m64, this works:

$ lipo -info lib/libboost_iostreams-xgcc42-mt.dylib
Architectures in the fat file: lib/libboost_iostreams-xgcc42-mt.dylib are:
i386 ppc7400 x86_64
