src/tools/make_etags creates link to TAGS file from each and every

My understanding of this and of the analogous structure in make_ctags
is to accommodate people who hadn't tuned up their text editor to do
the right thing. If we're going to revisit this, we should do both or
neither.

I'm for removing both and adding some minimal explanation of how not
to need the tags files all over the tree.

Best,
David.
