Added wrapper-subr.sh, which provides shell functions that are useful to

make the wrapper code less frightening. For example, instead of

    arg="${arg#-Wl,}"
    $debug_log $wrapperlog "   (transform-sunpro-cc) to: $arg"
    addtocache=yes

one can simply write

    transform_to "${arg-Wl,}"

The functions that are currently implemented are: transform_to,
transform_discard, transform_to_nocache, transform_discard,
transform_pass and transform_pass_unknown.
