Building coreboot and SeaBIOS from Windows

[Scott Duplichan]

The coreboot build environment for Windows is once again working:
http://notabs.org/coreboot/windows-build.htm (release 013).

SeaBIOS also builds, but requires a change not yet in
SEABIOS_STABLE. Use SEABIOS_MASTER for now. Thanks to
Kevin for that change:

Thanks,
Scott
