    Makefile: use if_change_dep for u-boot.cfg · fcd29a4d

    cmd_cpp_cfg generates a dependency output, but because it's invoked using
    if_changed rather than if_changed_dep, that dependency file is ignored.
    This results in Kbuild not knowing about which files u-boot.cfg depends
    on, so it may not be rebuilt when required.
    
    A practical result of this is that u-boot.cfg may continue to reference
    CONFIG_ options that no longer exist in the source tree, and this can
    cause the adhoc config options check to fail.
    
    This change modifies Makefile to use if_changed_dep, which in turn causes
    all dependencies to be known to the next make invocation.
