    microblaze: Remove _dl_skip_args usage
    
    Since ad43cac44a the generic code already shuffles the argv/envp/auxv
    on the stack to remove the ld.so own arguments and thus _dl_skip_args
    is always 0.   So there is no need to adjust the argc or argv.
    
    Checked with qemu-user that arguments are correctly passed on both
    constructors and main program.
