Summary: pdp mmx problems on amd64

Initial Comment:
pdp's "./configure --enable-mmx" leads to build failure on amd64:

make -C mmx
make[3]: Entering directory `/build/buildd/pd-pdp-0.12.svn20090813/system/mmx'
as -o pixel_pack_s16u8.o pixel_pack_s16u8.s

make[3]: *** [pixel_pack_s16u8.o] Error 1

it compiles fine on i386.

problem:

./configure doesn't automatically enable MMX if it is available, or disable it if requested but the CPU doesn't support it.

suggested fix:

add a test for build target CPU type in pdp/configure.ac and autoenable MMX if it is supported

suggested fix 2:

port the i386/mmx code to amd64/mmx, autoselect at compile time and/or run time
