--- Comment #2 from Pavel Minaev <int19h at gmail.com> ---
Even with DYNAMIC_ARCH enabled, OpenBLAS still tries to do CPU detection on the
build machine, and fails if the CPU type is unknown (note that this means that
it'll only manifest on machines with CPUs it is not aware of, which is probably
why this isn't happening for official package builds).

According to this bug in OpenBLAS tracker, this is by design:
https://github.com/xianyi/OpenBLAS/issues/1027

Their suggested workaround is to explicitly set the CPU type to some
low-featured CPU when building with DYNAMIC_ARCH (the actual CPU doesn't
actually matter, since it builds support for all of them - but at least it
allows the build to proceed).
