    x86: Add ix86_ifunc_ref_local_ok

    We can't always use the PLT entry as the function address for local IFU=
NC
    functions.  When the PIC register is needed for PLT call, indirect call
    via the PLT entry will fail since the PIC register may not be set up
    properly for indirect call.  Add ix86_ifunc_ref_local_ok to return false
    when the PLT entry can't be used as local IFUNC function pointers.
