[PATCH 5/5] libtoolize: install autoconf macros only if there is a $configure_ac.

[Gary V. Vaughan]

Applied as obvious.

* libtoolize.m4sh (func_install_pkgmacro_files): If there is no
$configure_ac in the parent project directory, and libtoolize is
in subproject mode, then the parent project has no use for
autoconf macros, so don't install them.
* NEWS: Updated.
