Build for MIPS N32 host fails due to references to 64-bit support code

collect2: error: ld returned 1 exit statusThe patch changes the code to not use these functions, as it does on 64-bit architectures. I don't know a more portable solution which wouldn't require changing when porting to every new 64-bit architecture with 32-bit pointers.
