Like the additions for ARM/aarch64, this fixes the elf/tst-protected1[ab]
tests on Nios II.  It does require a single liner patch to BFD to
define 'elf_backend_extern_protected_data', which I'll submit to upstream soon.

Tested and committed to master.

This should be the last fix I have for Nios II for 2.22, I'll be posting
the test results to the release wiki page soon.

Thanks,
Chung-Lin
