vgabios: fix compilation after x86emu changes

This utility links in coreboot code, and has been broken for a while
again after removing some hacks from coreboot. I hadn't realized how
bad it was broken last time, and since most of this stuff is still
in a pretty bad shape, I decided to throw all of the changes together.
