At the point where it's actually building and installing things to the
temproot there is a SUBDIR_OVERRIDE which restricts it to src/etc so
that shouldn't make any difference.

It's defined in src/Makefile.inc1. Try running the most recent version
of mergemaster that's in the tree, plus the patch above to
src/share/mk/ and it should work. It worked for me using a
clean DESTDIR, -i and -Aarm. I didn't specify a different src
directory as you did in the PR since I was using my regular stock src
tree (plus the patch above).
