$NetBSD: patch-src_libprelude-error_Makefile.in,v 1.2 2019/12/20 22:11:02 gutteridge Exp $

Use -P when preprocessing error symbols to avoid getting line number
output, which on gcc5 introduces extra line breaks and makes the
downstream processing fail miserably.

Also, rename the awk variable "namespace" to "name_space", since the
former is now a reserved word with GNU awk 5.0.
