Bug#812551: snap-aligner: FTBFS on non-x86: xmmintrin.h: No such file or directory

[Aaron M. Ucko]

Source: snap-aligner
Version: 0.18~1.0~beta.18+dfsg1-2
Severity: important
Justification: fails to build from source

Non-x86 builds of snap-aligner are still failing:

  SNAPLib/Compat.h:86:106: fatal error: xmmintrin.h: No such file or directory

I'd suggest changing the conditional here to

  #if defined(__SSE__)  &&  !defined(__APPLE__)

Thanks!
