sdl_gfx: don't use --enable-mmx on x86_64

Browse Source 
Even though the MMX instructions are available on x86_64 processors,
the MMX code in sdl_gfx is written in IA32-specific assembly code, and
therefore does not build on x86_64. It generates the following build
issues:

SDL_imageFilter.c: Assembler messages:
SDL_imageFilter.c:34: Error: `pusha' is not supported in 64-bit mode
SDL_imageFilter.c:38: Error: `popa' is not supported in 64-bit mode
SDL_imageFilter.c:77: Error: `pusha' is not supported in 64-bit mode
SDL_imageFilter.c:93: Error: `popa' is not supported in 64-bit mode
[...]

We fix this by only enabling MMX support in this package when the
processor supports MMX *and* it is a IA32 compatible processor.
