[coreboot] r3789 - trunk/coreboot-v2/util/options

[svn]

Author: stepan
Date: 2008-12-02 13:26:17 +0100 (Tue, 02 Dec 2008)
New Revision: 3789

Modified:
   trunk/coreboot-v2/util/options/build_opt_tbl.c
Log:
build_opt_tbl:
make sure the temporary files are created in the same directory as the
target files so they can be rename()d. This fixes a compilation issue on
machines with the build directory living on another partition than /tmp.
Pretty trivial.
