# ARCHFLAGS is a very convenient way of doing this for simple/obvious cores
# that don't need anything defined on the command line for 32 vs 64 bit
# systems, however it won't work for anything that does.  For that, you need
# to do two separate builds, one for each arch, and then do something like:
#  lipo -create core_i386.dylib core_x86_64.dylib -output core_ub.dylib
#
# If building on 10.5/10.6, it's possible that you could actually build a UB
# for Intel/PowerPC, but please don't. ;) Consider this a proof of concept
# for now just to test a few cores.
