[PD-dev] Quick tip for compiling objects on Snow Leopard

[Hans-Christoph Steiner]

We should get 64-bit builds going.  There is a part-time 10.5 build  
server, so it should be possible to make a 32/64-bit universal binary  
of the whole thing.  I wrote up a new, standalone Makefile that easily  
supports such builds, the idea is to have a single build system for  
each lib, and have it decentralized, instead of all in 'externals/ 
Makefile'.  Its in place for these libs in 'externals': apple, ext13,  
motex.  It should work with little effort for any lib that doesn't  
need ./configure (which is most).
