From 328c4c7fcefd02207b2a88ae95b841d9721afeec Mon Sep 17 00:00:00 2001
From: harti <harti@FreeBSD.org>
Date: Thu, 12 Aug 2004 11:49:55 +0000
Subject: Put variable assignments on .MAKEFLAGS and .MFLAGS targets into the
 .MAKEFLAGS variable so that these are also passed to sub-makes. This makes
 the handling of variables in the command environment more consistent.

PR:		bin/68853
