Wait, what?

The actual wording is:
"The rule is that if the file exists in the gcc tree then gcc owns it."
It originated from this thread,
https://sourceware.org/ml/gdb/2013-11/msg00025.html
That's not the first message in the thread, but that's where
I remember wanting to see something written down.

Perhaps kinda unfortunate for things like include/gdb/gdb-index.h.
But at least it's a rule that can be expressed in one sentence,
and I don't think it's been a problem.
