[Buildroot] [git commit] openblas: disable OpenMP

commit: https://git.buildroot.net/buildroot/commit/?id=fb45f199e509d05be4bc696b740f995918fe9eb6
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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.
