I have the same problems with the distribution NumPy package, but I can
use a locally-compiled NumPy with no patches.  It doesn't look like your
build has any patches either:
https://cygwin.com/cgi-bin2/package-cat.cgi?file=x86_64%2Fpython-numpy-src%2Fpython-numpy-1.22.0-1-src&grep=numpy
so that's fun.

Out of curiousity, what options are you passing for cpu-baseline and
cpu-dispatch?
https://numpy.org/devdocs/reference/simd/build-options.html
I don't see the newest cygport in the Cygwin package repository.
