Also add noinst_DATA to CHECK_DEPS; it's not needed in practice since
`make` will build noinst_DATA, but it's logically required and will
make a difference if any of the noinst_DATA sources change between
`make` and `make check`.
Tony Reix figured out why omitting packages from noinst_DATA didn't
seem to matter: because if gccgo can't find foo.gox, it will fall back
to reading the export data in foo.o, and foo.o will exist because
these packages go into libgo.a.
