    sparc64: Remove unwind information from signal return stubs [BZ#31244]
    Similar to sparc32 fix, remove the unwind information on the signal
    return stubs.  This fixes the regressions:
    FAIL: nptl/tst-cancel24-static
    FAIL: nptl/tst-cond8-static
    FAIL: nptl/tst-mutex8-static
    FAIL: nptl/tst-mutexpi8-static
    FAIL: nptl/tst-mutexpi9
    On sparc64-linux-gnu.
