Build still non-portable despite SAGE_FAT_BINARY=yes because of numpy #31565
Description
Follow-up from #29537, #31521.
Observed on cygwin-standard but likely also affects the Docker images and the Sage binary distribution.
With the upgrade to numpy 1.20.x (#31008), the non-portability shows as an error message instead of a crash:
[sagelib-9.4.beta0] from numpy.core._multiarray_umath import (
[sagelib-9.4.beta0] RuntimeError: NumPy was built with baseline optimizations:
