I didn't try hello-mod, but the two (proprietary) out-of-tree modules
that we routinely build into our own images do still compile and work.

I've tested on arm and mips.  I guess I can set up a build tree for a
qemu target on some other architecture if you like.

No, just force of habit.  Using xargs is more performant in general, but
"find -exec ..." is safer and I guess that's probably what we should do
here too.
