Bug#1043048: openblas: gives wrong results on mips64el, ignores test failures

[Rebecca N. Palmer]

Control: tags -1 upstream

Upstream CI's mips64 qemu test has what look like the same FATAL ERRORs, 
in MIPS64_GENERIC but not SICORTEX, but is still listed as passing.

Which suggests that they also have both parts of this bug (wrong answers 
on mips64el, and errors not actually failing the build), and that 
switching back to SICORTEX will probably work.
