The warning is not bogus, and there's no real error either.
The loongson jump fix does really replace a jump instruction with
multiple instructions that ends with a jump. This hack in our local source
is because we (NetBSD) don't want the warning in this specific case
(but we do want it if other macros cause one instruction to
be remplaced by multiple instructions). The alternatives are to
remove -mfix-loongson2f-jump (but then the hardware may hang) or
remove --fatal-warnings (but then we don't get errors when other
macros may cause real issues).
