Bug Description

Binary package hint: libatlas-base-dev

Currently, the on AMD64 the ATLAS generic build forces -fpmath=387, even though all processors that belong to this architecture support at least SSE2. This makes execution very slow, worse then using the standard implementation of blas from the package libblas, which is compiled using standard C flags that enable sse2 by default on AMD64.
