commit aa1faf7d39989817bb30b161d692647c8deac36f Author: Stefan Reinauer stefan.reinauer@coreboot.org Date: Tue Nov 1 21:43:50 2011 +0100
Add Python scripting to GDB.
This allows GDB to run Python scripts. The Python build is dependant on the GDB build flag.
Changes by Stefan Reinauer: - update to latest buildgcc script - disable GDB per default - disable python scripting, if GDB is not enabled - bump version number to 1.06
