Illegal instruction on x86 Qemu guest #272
Description
The OpenBLAS 0.2.8 Debian package for i386 (x86) fails to build. A test crashes with illegal instruction. The full build log is there:

I don't have access to the machine. However, if needed, I could try to replicate the problem by creating a similar Qemu guest.
