Extend x32 check by also checking for __x86_64__. Currently, the configure script checks for x32 by testing just the __ILP32__ define. However, on "plain" i386, __ILP32__ can also be defined, for example by clang 3.5.0 and higher. (That gcc does not define it there, is another issue, but not for this tracker.) Therefore, extend the check by also checking for __x86_64__, which will also be defined for x32. BUG=887 Change-Id: I90ac1d6843caff0416e1dd360c0be3dbaa85c2ae
