    depend-cleanup.sh: Handle commit cbdec8db18b5
    
    That commit changed libc to use the MI pdfork implementation, but with
    an incremental build the object file for the pdfork.S stub lingers and
    causes a linker error.
    
    Cleaning the depend file is not enouch, so modify clean_deps() to remove
    object files as well, and add a call to ensure that pdfork.*o is
    cleaned.  The new file is _pdfork.o.
