openblas: disable OpenMP
PATCH 1/1 openblas: disable OpenMP
For powerpc (and powerpc only), the openblas build system will enable USE_OPENMP when threads are enabled. But the toolchain wasn't necessarily built with OpenMP support. So explicitly disable OpenMP - for all architectures, not just powerpc, just to keep things simple.
We could have autodetected whether OpenMP is available at configure time, but that would be more of a feature patch, it's up to upstream to do that.
Fixes:
