Unfortunately we can't enable it for all N64 because it is not yet possible to
distinguish N32 from N64 from the triple on other environments.
N64 has been confirmed to produce identical (within reason) objects to GAS
during stage 2 of compiler recursion on N64-abi Fedora. Unfortunately,
Fedora's triples do not distinguish N32 from N64 so I can't enable it by
default there. I'm currently repeating this testing for Debian mips64el but
it's very unlikely to produce a different result.
