m4 has recently (as in really quite recently) been updated to a
new version, but it appears as if the infrastructure needed for
it to build as a tool on other systems than NetBSD hasn't been
put in place (or not fully yet).

You can file a PR about it, or just wait a bit longer (maybe a
day or two) and it will get fixed.

If you want a more stable environment for testing, I'd suggest
using the netbsd-11 branch, the stable branches rarely fail to
build (though occasionally), with HEAD, sometimes a suitable fix
takes a while.
