This adds a simple script to build a default toolchain for coreboot

compilation, to be independent of broken or missing OS/distribution tool chains. Signed-off-by: Stefan Reinauer <stepan@coresystems.de> Acked-by: Ronald G. Minnich <rminnich@gmail.com> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@4681 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
