why another check and condition, USE_ASM should be the one used
and runtime detection of mmx code is the only sensible way.

right now it does not compile on Mac OS X:

ld: .libs/libtheora_la-dct_decode.o has external relocation entries  
in non-writable section (__TEXT,__text) for symbols:

ld: .libs/libtheora_la-idct.o has external relocation entries in non- 
writable section (__TEXT,__text) for symbols:

does it work on 64bit?
