rseq/selftests: Add support for OpenRISC
Add support for OpenRISC in the rseq selftests. OpenRISC is 32-bit
only.
Tested this with:
Compiler: gcc version 14.2.0 (GCC)
Binutils: GNU assembler version 2.43.1 (or1k-smh-linux-gnu) using BFD version (GNU Binutils) 2.43.1.20241207
Linux: Linux buildroot 6.13.0-rc2-00005-g1fa73dd6c2d3-dirty #213 SMP Sat Dec 28 22:18:39 GMT 2024 openrisc GNU/Linux
Glibc: 2024-12-13 e4e49583d9 Stafford Horne or1k: Update libm-test-ulps
