The commit which migrated MIPS to gcc14 broke building on at least freebsd.

It looks like genmatch via libgcc requires libintl, which doesn't look like it's being built for gcc. texinfo builds its own version of libintl though?

I've captured a full log at https://people.freebsd.org/~adrian/netbsd/20251216-mips-post-gcc14-migration-build-fail-1.txt .
>How-To-Repeat:
* delete the obj/root directory
* build sgimips on freebsd-16 amd64
* wait
