[coreboot] v3 defconfig

[Myles Watson]

I'd like to make buildrom support v3 in the same way that it supports
v2.  I don't want buildrom to keep config files if it can help it.

I thought it would be the best to support make defconfig in the same
way that the kernel does.  I'd like to be able to type make defconfig
CONFIG_MAINBOARD_NAME=emulation/qemu-i386 and have it do the right
thing.

This patch doesn't work unfortunately, and I don't know why.
