[x264-devel] compilation failure on NetBSD (ssse3 related)

[hbent at cs.oberlin.edu]

After the large intra asm pred commit x264 no longer compiles on NetBSD 5.
 This appears to be because it is unconditionally emitting SSSE3
instructions, which binutils 2.16.1 doesn't understand.  Perhaps there
should be ifdefs around the ssse3 (and perhaps sse2?) functions.
