Based on contents from coreboot wiki[1], this patch adds much needed
documentation for the very important abuild utility.
On top of what was there:
- Mainboard targets have been updated
- Added example for building one variant of one board
- Added example for building boards selectively and/or with custom
configurations using --skip_set/--skip_unset, -K, and config files
