more toplevel targets I'd like to slay... please comment.

[Nathanael Nerode]

These are subdirs which are refered to at the top level, but which
probably don't *ever* exist.  I'd like to get rid of the support code
for them.

cvssrc: I don't know why this isn't just 'cvs', and in any case the 
references seem to be bitrotted.  Anyone know why this is in here at
all?

send-pr: Seems to be superseded by other tools.
prms: Looks like it was too.

ispell: emacs-dependent, and we don't do emacs in this tree any more.

inet: Seems to be dead, and probably doesn't belong in this tree anyway.

gdbtest:  Looks like a relic of some previous experiment.
tgas:  Looks like a relic.

target-qthreads: Looks like a leftover.

libstub: Looks like it's gone, presumably superseded by something else.

Please tell me what I can kill. :-)
