Numba and llvmlite won't install on sage cygwin

Even under admin on SageMath 9.1 Shell I'm unable to install numba (buildchain is probably broken, is there a workaround -- conda install?). Numba would help reshape matrices and stuff.

So here's basically an error:

$ sage --pip install numba

I think the issue here is fairly clear: llvmlite, which is a dependency of numba, does not support Cygwin.

It appears that in the llvmlite build script there is an explicit check of supported platforms, which does not currently include cygwin. There is, however, a somewhat recent pull request to add cygwin support, but it has not been reviewed yet.

P.S. conda does not support cygwin
