Potentially speed up ccache builds

This might speed up ccache builds. While direct mode is faster in
    evaluating if files changed, the special situation of coreboot prevents
    ccache from using build results of previously built boards in the same
    run.

This is because Kconfig adds board information to config.h which is
    part of the hashed data set in direct mode. In preprocessor mode the
    preprocessor copes with them before ccache decides if the file is the
    same.
