    MIPS: Add ELF file header flags
    
    Now binutils use some E_MIPS_* macros and EF_MIPS_* macros, it is
    difficult to decide which style macro we should use when we want
    to add new ELF file header flags.
    IRIX used to use EF_MIPS_* macros and in elf/elf.h there also has
    comments "The following are unofficial names and should not be used".
    So we should use EF_MIPS_* to keep same style with the beginning.
