Remake configure/config.h.in/etc.

[Wayne Davison]

Since multiple people have applied my UseLogin patch and failed to get
it to work because configure/config.h.in were not automatically rebuilt,
I decided it was time to add some rules to the Makefiles to update these
things.  The appended patch will cause a "make" to rebuild configure,
config.h.in, config.h, and both Makefiles if the appropriate source
file(s) change.  It will also run "./config.status --recheck" if
configure is rebuilt.
