new: maintainer mode.
There is now a ./configure --maintainer mode which establishes
a variable called maintainer in config.make, with a y value.
The initial use for maintainer mode will be that the Yacc
parser (the y.tab.c and y.tab.h) files will no longer be
regenerated whenever the parser.y file is newer.
In the following commit, I will add a generated parser.
* Makefile (y.tab.h, y.tab.c): These rules are now only
enabled in maintainer mode via an ifeq.
* configure (maintainer): New variable.
(gen_config_make): Generate maintainer make variable
definition in config.make.
