Comment(by jeremyhu@…):

 Since ML is now out, I can now discuss this.

 netpbm needs to change.  clang is behaving correctly.  netpbm assumes that
 it has access to __builtin_ia32_pcmpeqb128, but it doesn't.  clang dropped
 suport for the GCC-specific builtin and now supports the standard
 _mm_cmpeq_epi8.
