    gcc80: Various cleanups and tweaks to makefiles
    
    - Remove unused variables.
    - Remove some commented directives.
    - Remove unneeded '-I${.CURDIR}' from cc_tools/libcpp/Makefile.
    - Fix multiple comments: typos, filenames, punctuations, etc.
    - Change two unnecessary '+=' to be '='.
    - Include <bsd.subdir.mk> for 'cc_tools/Makefile' to make more sense.
    - Add a brief description for the origin of 'Makefile.zhack'.
