Toplevel patch: determine 'install'ed subdirs at configure time

[Nathanael Nerode]

This replaces the dependencies of 'install' with dependencies determined
at configure time.  It depends on my previous patches being in.  For 3.4bib.

Tested by configuring on i686-pc-linux-gnu.  Everything works the way
it's supposed to.  Yay!

Together with my previous outstanding patches this clears the way for 
some large autogeneration changes which will come soon.

	* Makefile.tpl: Determine subdirs to 'install' at configure time.
	* configure.in: Determine subdirs to 'install' at configure time.
	Remove bogus exports.  Normalize style.
	* Makefile.in: Regenerate.
