From 4a0f7538c5c0805fd9a791967bbabacc41deadd9 Mon Sep 17 00:00:00 2001 From: Wolfgang Denk Date: Tue, 16 Dec 2008 14:41:02 +0100 Subject: [PATCH] Makefile: fix dependency problem with parallel builds Parallel builds (using "make -jN") would occasionally fail with error messages like include/autoconf.mk:212: *** missing separator. Stop. Line numbers and affected boards were changing. Obviously some Makefiles included autoconf.mk while it was still being written to. As a fix, we now write to a temporary file first and then rename it, so that it is really ready to use as soon as it appears.
