Hi Daisuke,

Can you please replace the add-ppc64-v5.patch with the attached add-ppc64-v6.patch?

The change consists of one line that replaces the (non-existent) "PPC64LE" test 
with the __BYTE_ORDER test:
  
  +ifndef ELF_DATA
  +#ifdef PPC64LE
  +#define ELF_DATA ELFDATA2LSB
  +#else
  +#define ELF_DATA ELFDATA2MSB
  +#endif
  +#endif
  
to this:
  
  +#ifndef ELF_DATA
  +#if __BYTE_ORDER == __LITTLE_ENDIAN
  +#define ELF_DATA ELFDATA2LSB
  +#else
  +#define ELF_DATA ELFDATA2MSB
  +#endif
  +#endif

Actually it's highly unlikely that ELF_DATA will *not* be defined, but
just in case there are distributions where the #include file path does 
not pick up /usr/include/asm/elf.h, then the change above will resolve it.

Thanks,
  Dave
