[PATCH v4] build: write VERSION 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 to the user to examine. The contents of the VERSION file
is seldom read by the build system itself as the $(VERSION)
variable has the same information.

ctested also with:
mv .git .x
make
cat VERSION version
mv .x .git
make
cat VERSION version
