It is a false positive. With ARM64_SUBTARGETS empty the loop expands to
"for DIR in ; do ... done", which POSIX allows: the word list after "in"
may be empty, so the body never runs. The $(if) sets ret to 0 for that
case, so the target succeeds.

I ran the patched Makefile with ARCH=x86_64 for all, install and
emit_tests under bash, dash and busybox sh, with and without
FORCE_TARGETS=1. Every combination exits 0 with no output.
