[PATCH, testsuite]: Add ieee options for gcc.dg/torture/pr68264.c

[Uros Bizjak]

This test uses NaN, so it requires ieee options for certain targets.

2015-11-17  Uros Bizjak  <ubizjak@gmail.com>

    * gcc.dg/torture/pr68264.c: Use dg-add-options ieee.

Tested on alphaev68-linux-gnu and committed to mainline SVN.

Uros.
