Can't compile libatlas at Xeon E5-2650v2 and 2620v2 with ARCH detected by default Corei2.
If I change ARCH to Atom64AVX copilation and tests are successful, but results are worse
I suggest wrong file name for output file.
Same problem reported at https://sourceforge.net/p/math-atlas/support-requests/996/#351f
I have tested v3.11.34 ... 41, error message:
