Fix our makefile rule so the target binaries are getting linked -g

Basically this isn't working right now because BINTARGETS is getting
defined after Make.rules is evaluated.  But there's no actual reason we
need BINTARGETS in the rule, so long as every binary has a %.o object,
which we can make always be true easily enough.
