    rtla: Add the ability to create ctags and etags

    - Add the ability to create and remove ctags and etags, using the following
    make tags
    make TAGS
    make tags_clean

    - fix a comment in Makefile.rtla with the correct spelling and don't
      imply that the ability to create an rtla tarball will be removed
