x32: Check __ILP32__ instead of __LP64__ for x32
Check __LP64__ isn't a reliable way to tell if we are compiling for x32
since __LP64__ isnn't specified by x86-64 psABI. Not all x86-64
compilers define __LP64__, which was added to GCC 3.3. The updated x32
psABI:

definse _ILP32 and __ILP32__ for x32. GCC trunk and 4.7 branch have
been updated to define _ILP32 and __ILP32__ for x32. This patch
replaces __LP64__ check with __ILP32__.
