Comment (by NicosPavlov):

 As mentioned by Michael, the *-devel port might be worth trying, as there
 have been some commits these past few days in OpenBLAS addressing issues
 in configuring the code to compile AVX512 instructions.

 If that does not work, I attached a patch that would provide a quick fix,
 by disabling the -march flag when calling the gfortran compiler.

 I do not have the possibility of checking that issue, so I would be
 grateful if someone could confirm the fix.
