Close - plain config.mak.

I set $prefix there and ran "make install-doc".  That installed the man
pages in Documentation/share/man/ in my Git source directory.

Would it be sensible to define the values for these variables (with
absolute paths) in a separate top-level file like config.mak.uname
(defaults.mak maybe?) and include that in both Documentation/Makefile
and Makefile, then calculate the relative path from $(prefix) to
$({man,html,info}dir) for the compiled-in values.
