Thanks, these are easy enough for me to fix up.

Hmm.. ancient shelved toolchain. Perhaps this is the excuse we need to
say goodbye to arch/metag/...
Might be worth a thought. The metag toolchain doesn't even build anymore
without tweaking. gcc 4.2.4 doesn't build with a modern gcc, the metag
buildroot on github points to a no longer existing daily snapshot of
uclibc, and ToT uclibc doesn't build with gcc 4.2.4.
