<summary>Changes</summary>
Add `mips{,el,64,64el}-unknown-elf` to the set of triples claimed by the
BareMetal toolchain, mirroring the existing handling for
`riscv{32,64}-unknown-elf`, `x86{,_64}-unknown-elf`, and
`powerpc*-unknown-eabi`.
This is required for creating RockBox LLVM port (see
https://gerrit.rockbox.org/r/c/rockbox/+/7466).
