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: https://sites.google.com/site/x32abi/documents 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__. Signed-off-by: H.J. Lu <hjl.tools@gmail.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com>
