Hi!

Looking at the m4 file for kernel-devel it seems we only use the
LINUX_VERSION in order to construct the LINUX_DIR path and the rest of
the code, i.e. include/mk/module.mk uses the LINUX_VERSION_MAJOR and
LINUX_VERSION_MINOR generated based on the LINUX_DIR.
What is the LINUX_VERSION variable needed for? It does not seem to be
used anywhere outside the m4 kernel devel file.
