Follow-up Comment #31:

Found this report on the tracker for OpenBLAS:
https://github.com/xianyi/OpenBLAS/issues/3139

IIUC, we should configure OpenBLAS with TARGET=GENERIC instead of selecting a
specific (old) architecture. When I last tried to understand their build
instructions, I didn't realize there was a GENERIC target at all.
Afaict, the complete set of switches they suggest for binaries targeting
dynamic architectures is "DYNAMIC_ARCH=1 DYNAMIC_OLDER=1 TARGET=GENERIC". We
are already setting the former two.
Maybe that will also prevent that the resulting binaries depend on the build
host.

Re-opening report.
