[patch] gdbserver usage message improvement

[Martin Pool <mbp@samba.org>]

[I previously sent this to bug-gdb, but it looks like the newsgroup is
just full of spam, so I thought I'd resend it here.]

This small patch brings gdbserver's usage message up to date with the
manual, so that it indicates it can support TCP as well as serial
connections.  I remember being puzzled by this in the past, so I think
it would make gdb more friendly to have the message correct.

As far as I can see TCP is supported on all platforms where gdbserver
builds.

Thanks,
