Create a new internal interface for defining new make functions.

This allows us to create new functions without changing function.c.
You still have to modify the GNU make code (for now) though: this is
simply a preliminary step to possibly allowing make to load modules.

Modify the Guile integration to use this method rather than ifdefs
in function.c.
