commit d1f7cf4195bf3b1cca86f2b78eb0625411479706 Author: Stefan Reinauer stefan.reinauer@coreboot.org Date: Tue Nov 1 22:39:41 2011 +0100
buildgcc: Update coreboot reference toolchain to gcc 4.6.2
In addition: - drop some unneeded patches - make the scripting support depend on SKIPPYTHON not SKIPGDB so it is possible to build GDB with and without scripting support - rename the repository checkout version of GCC trunk, not X+1 so we don't have to change it on every version upgrade.
