From a75a770595079619e61e1623698e420427924cf9 Mon Sep 17 00:00:00 2001
From: Alexey Neyman <stilor@att.net>

Subject: Make the proc_service.h workaround apply to gdbserver

... when it is compiled without the native GDB.

Also, fix the gdbserver to be installed without a program prefix in this
case, as it was before the unification of the GDB backend.
