* src/smooth/ftgrays.c: Fix compilation if `FT_LONG64` is undefined. 

The code assumed that if `__SSE2__` is defined, then 64-bit integer
types are available.  This is not the case apparently for certain
multilib compiler targets like 'x86_32.x86' used by Gentoo.

This patch fixes the issue by disabling the special code path when
64-bit integer types are not available.

Fixes #1071.
