OpenBLAS: Failed to build OpenBLAS on skylake-x target.
I can’t build OpenBLAS with gcc-10.0.1 . This happened just recently (after thursday). and I don’t know if it is bug with gcc or openblas.

Ah sorry, this is a defect in the cmake setup and I was always testing with plain gmake. The file cmake/cc.cmake needs adding
I’ll push a PR for this in a minute
