Fix coreboot makefiles not to produce half baked output.
There were cases where output file was generated and modified within
a recipe. If make was interrupted, it could exit with an output file
that appears as up-to-date, but was generated with incomplete recipe.
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.
