    build: fix distcheck
    
    Now that distcheck no longer fails (see previous commit), let's
    address the shortcomings.
    
    * Makefile.am (CLEANDIRS, clean-local): New.
    * doc/local.mk, examples/calc++/local.mk, examples/local.mk,
    * examples/mfcalc/local.mk, examples/rpcalc/local.mk,
    * src/local.mk
    (CLEANDIRS): Get rid of Apple's *.dSYM directories.
    (CLEANFILES): Get rid of *.output files.
    * examples/variant-11.yy, examples/variant.yy: Don't generate
    any of the auxiliary files (location.hh and the like).
