It looks like you'll need to fix https://dxr.mozilla.org/mozilla-esr38/source/js/src/configure.in#2121 to take mips64 into account, though presumably there's a reason why mips64 didn't get handled specially by that case statement in the first place, and there might be more stuff to fix after that.  It looks like esr38 doesn't have support for mips64 in the JIT; esr45 might, though.

In any event, esr38 is no longer supported.  We'd take patches for current mozilla-central; it looks like mips64 detection works correctly there.
