    Revert "MIPS: add .module mipsREV to all output asm file"
    
    This reverts commit d904008df267cbcc01bd6edf98fa0789fb6e94da.
    
    ".module MIPSRev" has higher priority than -march=octeon or like.
    It makes assembler cannot recognize the extension instructions
    of octeon (See pr62030-octeon.c).
