libc/eglibc: enable rpc in eglibc-2.16+

While eglibc-2.16 recommends to use TI-RPC instead of the old sunrpc, the
old one can be included using a configure option. Since the user can still
use TI-RPC to override the libc implementation, we enable rpc unconditionally.

     8 # It is expected that this script is only to be run from the

    10 # paths.sh (we can't use  ". paths.sh", as POSIX states that
    11 # $PATH should be searched for, and $PATH most probably doe
    12 # not include "."), hence the "./".

    17 Usage: ${myname} <src_dir> <dst_dir> <base> <inc> [sed_re]
    18     Renumbers all patches found in 'src_dir', starting at 'base', with an
    19     increment of 'inc', and puts the renumbered patches in 'dst_dir'.
    20     Leading digits are replaced with the new indexes, and a subsequent '_'
    21     is replaced with a '-'.
    22     If 'sed_re' is given, it is interpreted as a valid sed expression, and
    23     is be applied to the patch name.
    24     If the environment variable FAKE is set to 'y', then nothing gets done,
    25     the command to run is only be printed, and not executed (so you can
    26     check beforehand).
    27     'dst_dir' must not yet exist.
