PatchSet 230

Author: ru
Log:
Added the MAKE_VERSION global that could be useful in determining
if a given make(1) is feature-compatible with a set of makefiles.

When merged, this will be used to replace the ugly upgrade_checks
hacks in src/Makefile.

Version has the RYYYYMMDDX format, where R is from RELENG_<R> and
X allows for 10 distinguishable changes per day.
