[PATCH] rtla: Add the ability to create ctags and etags

[John Kacur <jkacur@redhat.com>]

- 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
