equery depends gets it's output directly from the ebuild, it is not a
list of what *you* have and how you are affected.

The ebuilds are saying that if you have "tk" in USE, then portage must
install tk. Same with tcl.

So it all depends on what you have in USE.
We don't know what you need or want, that is your call. If you know you
need tk/tcl then add it to USE. If you don't need them, let them be
depcleaned. If you are not sure, let them be depcleaned and if stuff
breaks, then add them back to USE and update world.
