Thanks, Tom!

Eli, do the NEWS / docs changes look good to you?
(https://sourceware.org/ml/gdb-patches/2019-09/msg00067.html)

I just noticed that the MAINTAINERS entry is obsolete, then.
In some cases, we've simply removed those when removing a target,
but in others they were marked "Deleted".  What should we do here?

Bye,
Ulrich
