Automake 1.5.
* Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
(AMTAR): Help automake define it.
(INSTALL, install-data-hook): The INSTALL.txt trick is no longer
needed, 1.5 can have a macro and a target with the same name.
* m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
* m4/strip.m4: New.
* m4/init.m4, m4/sanity.m4: Update.
* doc/Makefile.am (CLEANFILES): 1.5 knows the texi2dvi files.
* lib/autoconf/Makefile.am, lib/autotest/Makefile.am,
* lib/m4sugar/Makefile.am, lib/autoscan/Makefile.am,
* lib/Autom4te/Makefile.am, man/Makefile.am: Use dist/nodist.
