Update .version file more aggressively.
* Makefile.am: Regenerate a temporary version string file on every
build, but update the real version file's mtime only if its contents
change.
(.version.tree): New target. Mark it phony, populating it with
`$(VERSION)` with every `make` if the `.tarball-version` file {created
by `dist-hook`} doesn't exist.
($(top_srcdir)/.version): Depend on foregoing target. If the tarball
version file and the target do not exist, copy `.tree` file into
place. Compare this file with `.tree` file; if they differ, move the
`.tree` file to this one.
(MOSTLYCLEANFILES): Add `.version.tree`.
Fixes <https://savannah.gnu.org/bugs/?61052>. Thanks to Bjarni Ingi
Gislason for the report.
