    Fix nios2 localplt failure
    
    Building for nios2-linux-gnu has recently started showing a localplt
    test failure, arising from a reference to __floatunsidf from
    getloadavg after commit b5c8a3aa82f66f49b731ca5204104cee48bccfa5
    ("Linux: implement getloadavg(3) using sysinfo(2)") (this is an
    architecture with soft-fp in libc).  Add this as a permitted local PLT
    reference in localplt.data.
    
    Tested with build-many-glibcs.py for nios2-linux-gnu.
