Port(1) supports for universal builds is not good enough to handle non-trivial cases. We currently try to develop mechanisms to overcome this, so we can make more ports build universal more easily.

Approaches

• Adding the universal build flags (-arch ppc -arch ppc64 ..) to the compiler flags: Suited for straight compilation of executables
• Adding universal build flags to the CFLAGS etc.: Suited for certain autotool driven builds
• Separating builds for different architectures, merging the different (single-arch) destroots (emulation or multiple build machines differing in arch may be necessary for some ports)
