[coreboot] Falco fails make with both standard compiler and reference toolchain

[radgokart]

Has anyone been able to get coreboot built for falco? Chromium doc lists a
process for it, and menuconfig has the options for it, but I get make
errors with both ubuntu's compiler and coreboot's cross compiler...
