Test failure not connected, comes from the doctests failing. See #13096

@andreas-schwab does numpy build/run/pass tests on riscv?

[andreas-schwab]

All except of numpy.core.tests.test_numeric.TestBoolCmp.

[mattip]

Cool . I do see another couple of patches, is the remove-__declspec.patch still needed to reduce warnings?

[andreas-schwab]

I don't know about the other patches, I do not maintain the openSUSE package.

Thanks @andreas-schwab
