[coreboot] r3777 - in trunk/coreboot-v2: src/config util/newconfig

Author: oxygene
Date: 2008-11-28 12:56:27 +0100 (Fri, 28 Nov 2008)
New Revision: 3777

Modified:
   trunk/coreboot-v2/src/config/Config.lb
   trunk/coreboot-v2/util/newconfig/config.g
Log:
This patch fixes the ugly race condition created through build_opt_tbl
running twice at the same time, overwriting its output files. This caused
a depending rule to produce an object file with no symbols in it.

This should silence up the regularly happening build failure messages on
the mailing list since we moved to the newer, much faster server.
