This updates SmiEntry.S to match the logic in SmiEntry.asm and SmiEntry.nasm. The default BUILDRULEORDER has .nasm higher priority than .asm or .S, so this issue was not seen with MSFT or GCC tool chain families. The XCODE5 tool chain overrides the BUILDRULEORDER with .S higher than .nasm, so this issue was only seen when using XCODE5 tool chain when IA32 SMM is enabled.
