Fix coreboot makefiles not to produce half baked output.
It looks like the cbfstool utility generates the output file even when it fails to generate it properly. This causes make, if started second time in a row, after cbfstool failure, to continue beyond the point of failure (as the corrupted output file is present in the output tree, the second make invocation presumes that it is valid, as it is newer than the dependencies). The output file should be created only when successful, in an atomic operation. There could be other places in the make system which require a similar fix, this needs to be investigated further.
