So there is an issue I need to resolve in that the notes can get lost if you
use --gc-sections which LLVM does when building the cross toolchain (so the
trick of using .comdat for notes doesn't end up working out). Right now it
only fully breaks RISC-V since all the other arches still have FreeBSD set
as the ELF OSABI in the ELF header.
