    Fix ldbl-128 rintl/nearbyintl just like flt-32 variants.
    
        * sysdeps/ieee754/ldbl-128/s_nearbyintl.c (__nearbyintl): Do not
        manipulate bits before adding and subtracting TWO112[sx].
        * sysdeps/ieee754/ldbl-128/s_rintl.c (__rintl): Likewise.

to the patches to backport for this issue as well.
