Configure + Makefile : simplification when -local

 When local=true:

 - "make install" is now a no-op
 - In configure, no need hence to fill the various variables
   about installation (BINDIR, COQLIBINSTALL, MANDIR,
   DOCDIR, EMACSLIB). This avoids many references to
   absolute location of the coq sources (which may contain
   blanks or other strange chars in win32).
 - For the moment, we keep CONFIGDIR and DATADIR, used when
   launching coqide from inside the build directory.
