gh-95855: Refactor platform triplet detection code, add detection for MIPS soft float and musl libc (#107221)
- Move platform triplet detection code into Misc/platform_triplet.c - Refactor MIPS detection, use defined(__mips64) to detect MIPS64 - Compute libc values in separate section - Add detection for MIPS soft float - Add detection for musl musl supports SPE with its soft-float ABI: https://git.musl-libc.org/cgit/musl/commit/?id=7be59733d71ada3a32a98622507399253f1d5e48 Original patch by Christian Heimes.
