Please don't, unless you are confident your change can satisfy
_everybody_.

People with makefile needs that are more "advanced" (that is,
something a simple "-include config.mak" cannot easily satisfy)
can do any number of things without touching Makefile I ship.
Examples include:

 - have own makefile, include Makefile.

 - have onw Make script, run "make -f Makefile" with preset
   "bindir=HERE NO_XXX=NoThanks" to reduce typing.

 - have own makefile, whose build target depends on Make.file
   and runs "make -f Make.file", with a build rule for Make.file
   to munge Makefile using custom perl/sed into it.
