added to 7.7-branch wiki: Re: RFA [PATCH] Implement 'catch syscall' for gdbserver

[Joel Brobecker <brobecker@adacore.com>]

For the record, since this patch has been submitted in a reasonable
timeframe prior to the planned 7.7 branch creation, I've added it
to our 7.7 release wiki page. It does not mean that we must get
this patch in the release (for instance if considered too risky),
but hopefully this will place this patch a little higher on the
reviewing queue...

Thank you :)
