OpenBLAS: openblas-0.3.10 build failure on dynamic zarch

openblas-0.3.10 fails to build in Fedora s390x with DYNAMIC_ARCH=1 DYNAMIC_OLDER=1. I get a link error

This should probably be unified with the section already containing various other gcc version tests in Makefile.system (there is already a “major version >4”, and at least one test for a particular minor version IIRC)
