    fork in libpthread cannot use IFUNC resolver [BZ #19861]

    This commit only addresses the fork case, the vfork case has to be a
    tail call, which is why the generic code needs an IFUNC resolver
    there.

    (cherry picked from commit f06f3f05b48c72e2c9b0fa78671f94fd22d67da8)
    (cherry picked from commit 1915d6d182a55d1eb852643a78ac24bc17783fb0)
