Is there a reason you can't change `lib := nonlib` to `lib :=
testsuite` in the invocation of libof-iterator.mk, instead?  Several
other places in the Makefile would need to be changed, but using the
testsuite module is abstractly more appropriate and might have other
desirable effects in the future (e.g. not including libc-symbols.h at
all).
