[PATCH] Fix nearbyintl linkage for ia64 (bug 19219)

[Adhemerval Zanella]

GLIBC fails to build for ia64 since commit d0d286d32dda654f8983e8fe77bca0a2cda2051b.
It is because this commit uses the internal definition for nearbyintl,
but ia64 specialized implementation (sysdeps/ia64/fpu/s_nearbyintl.S)
does not define it.

Tested with a ia64 build.

        [BZ #19219]
        * sysdeps/ia64/fpu/s_nearbyintl.S (__nearbyint): Define and
        weak_alias to nearbyintl.
