Separate some AC_SUBST / AC_DEFINE
Eventually, the RTS configure alone will need the vast majority of
AC_DEFINE, and the top-level configure will need the most AC_SUBST. By
removing the "side effects" of the macros like this we make them more
reusable so they can be shared between the two configures without doing
too much.
