[coreboot] Coreboot overwrites seabios .config at build time

[HighlyCaffeinated]

If any options are changed in Seabios - either via direct editing of the .config file or by 'make menuconfig' in the build/seabios directory, those changes are overwritten by coreboot during before it begins the seabios build. How can this behavior be stopped such that seabios configuration is possible?

Thanks,
Todd
