Helps compile on riscv32

@kraj I think this should also be added to numpy/core/include/numpy/npy_endian.h. Does the full test suit pass with this patch? @aurel32 this may be a long shot, but since you added RISCV64, does this make sense to you?

@seberg so far I have only fixed build, I am in process of setting up a test run in qemu/riscv32

this is riscv32 emulation on qemu. So I might have to see whats going on.

[charris]

@kraj Any progress?

[kraj]

@charris I think the test results above hold, for my purposes its working ok.

[kanavin]

@kraj this needs rebase on latest target commit

[charris]

close/reopen to see if Mac problem goes away.

[charris]

close/reopen

Successful CI run, is anything blocking this from merging?
