    build: Correctly list out generated sources and their dependencies
    
    Sources that are generated during the build should be listed under
    BUILT_SOURCES [1]. Their dependencies should be in EXTRA_DIST so that
    they can be generated when building from a tarball, and they should
    get cleaned by "make clean" like every other artifact produced by
    "make".
