Dear maintainer,

while looking at the bug I recognized, that the AMD Athlon(tm) II X2
255 Processor is not capable to handle SSE4.1 opcodes. The SSE4.1 and
SSE4.2 support by AMD CPUs was introduced later.

I rebuild the Package without these flags (-msse4.1 / -maes) and
everything works as expected. I also removed the -maes flag, since AES
is, like SSE4.1, is not part of the Debian amd64 architectural
baseline. Patch is attached.

Regards
    Benedikt Spranger
