build: write version.stamp file containing $(VERSION) string

This version file will be as prerequisite to the target files
that use the version info for some purpose, like printing
it for the user to examine. The contents of the version.stamp
file is seldom read by the build system itself as the $(VERSION)
variable has the same information.

Thanks to Trevor, David and Mark for their contributions.
