Universal binary support in scons on mac

[abs1nth]

It's off by default ( as it's just extra build time for developers ), but to enable it, specify the option "universal=all".

great news!
does building with scons have the distinction between development and release/deployment builds? if so we could mimic what XCode does, namely building just for $NATIVE_ARCH when in development build and make an universal binary when doing an deployment/release build.

However, the 10.4u SDK supports 4-architecture binaries ( ppc_64, i386_64, ppc, i386)..

it really doesn't (support 4 architectures). 64-bit applications are only supported for non-gui applications (command line). that is why they are making that big fuss over 64 bit support in 10.5.
