$NetBSD: patch-config_rules_mk,v 1.1 2011/10/14 01:01:55 dholland Exp $

Sleazy patch to hack around incompatibility between gmake and perl.

(Without this perl spews "syntax error at -e line ##, near ..." for,
AFAICT, any line that begins with a keyword. It is because gmake is
passing the backslashes through; sh of course preserves them within
single quotes, so they get to perl, and perl really doesn't like what
it apparently considers stray backslashes all over the script text.
Naturally, you can't *not* have the backslashes, or gmake won't allow
the thing to span multiple lines. Hurray for gmake.)
