build system: Don't run the full build system on "make clean"

When running "make clean" the build system used to parse the entire
    build system. Besides costing time, it prevents cleaning the tree
    if a blobs-board is selected but blobs are not enabled.

Instead, clean always removes all of $(obj) and .xcompile, while
    distclean additionally removes .config and the like.

Besides cleaning up more completely (eg. dependency files), a side
    effect is that this also removes $(obj)/util, if it exists
    (default location for build tools).
