The os specific part is handling the executable format. The JIT we'd be
using (MCJIT) has support for ELF, MachO, and COFF. The architecture
specific bits seem to be there for x86, arm (small endian, be), aarch64
(arm 64 bits be/le again), mips, ppc64.

Somebody is working on RISC-V support for llvm (i.e. it appears to be
working, but is not merged) - but given it's not integrated into gcc
either, I'm not seing that being an argument.
