[PATCH] autoconf: Set mandir in config.mak.in and export variables not in Makefile

[Jakub Narebski <jnareb@gmail.com>]

This patch with the previous "[PATCH] Allow INSTALL, bindir, mandir to
be set in main Makefile" patch allows ./configure script to set where
manpages will be installed using --mandir=DIR (./configure defaults to
PREFIX/man).
