[PD] osx universal binaries for externals ?

the easiest approach is to make separate externals for each architecture 
(like ppc, ppc64, i386) and glue them together with lipo.

lipo -create myext.i386.pd_darwin myext.ppc.pd_darwin -output 
myext.pd_darwin

The flext build system uses a slightly different approach by compiling 
architecture-specific object files (because the compiler flags may be 
architecture-specific), use lipo to make UB object files and then call 
the linker with something like
g++ -dynamic -arch i386 -arch ppc -isysroot 
/Developer/SDKs/MacOSX10.4u.sdk -o myext.pd_darwin  objectfiles....
