$NetBSD: patch-Makefile,v 1.1 2020/11/29 03:11:54 dholland Exp $

Build the preprocessor front end thingy with -g instead of with -O2.

With -O2 it crashes with a message about EOF inside a string constant;
this has been happening with clang for a while and gcc recently joined
the party. With just -O, it loops forever instead for me, which isn't
an improvement.

This should serve as a workaround until someone gets around to
figuring out where the undefined behavior is.
