Support DESTDIR and PREFIX variables in Makefile 

* Add support for DESTDIR and PREFIX variables in Makefile.
  PREFIX defaults to /usr and DESTDIR is not defined by default.
* Redefine MANDIR and BINDIR in function of PREFIX and DESTDIR. Note
  that DESTDIR for overriden variables (variables defined via make
  VAR=value construct)
