Since the bootstrap process requires that several of the rules for
files generated in doc and tests already lived in
$top_srcdir/Makefile.am, along with proxy rules in sub-Makefiles,
this changeset consolidates almost everything into the top
Makefile.am, simplifying things considerably:

* doc/Makefile.am, tests/Makefile.am: Removed.  All rules moved...
* Makefile.am: ...to here and adjusted to run from $top_builddir.
simplify with respect to removing much of the make recursion.
Add `doc/PLATFORMS', `doc/fdl.texi' and `doc/notes.texi'.
`defs.in' and `defs.m4sh' are in directory `tests'.
(uninstall-hook): Don't forget to uninstall libtoolize's libltdl
source tree.
(lt__cd): New make macros to work around problems with CDPATH in
some shells.
* bootstrap: Simplified dirty makefile management, and bootstrap
file creation in light of having only a single pertinent
Makefile.
* configure.ac (CONF_SUBDIRS): Add tests/ prefix to each subdir to
compensate.
(DIST_MAKEFILE_LIST): Adjust.
(AC_CONFIG_FILES): Remove doc/Makefile and tests/Makefile.
* tests/defs.m4sh (LIBTOOL, scripts): Adjust paths.
