Makefile: FHS conformant manpage installation pathes

Browse Source 
FHS mandates manpages should go to /usr/share/man (or /usr/local/share/man,
for site local installations) -- /usr/man was an fallout of some ancient
Unices that haven't been fully FHS conformant and usually just a symlink to
/usr/share/man, if existing at all.

Distros sometimes need to override this (eg. MVCC installs), therefore go
the 30+ years common practise way and introduce MANDIR environment variable.
Since it's a subdir under the prefix for general constant and machine
architecture independ data -- which in turn also sometimes wants to be
overridden by distros, it shall be derived from DATADIR variable.
