[PATCH RFC libdrm 1/2] intel: Improve checks for big-endian

[Geert Uytterhoeven]

  - sparc64-linux-gnu-gcc does not define __BIG_ENDIAN__ or SPARC, but
    does define __sparc__, hence replace the check for SPARC by a check
    for __sparc__,
  - powerpc{,64,64}-linux-gnu-gcc does not define __ppc__ or __ppc64__,
    but does define __BIG_ENDIAN__.
    powerpc64le-linux-gnu-gcc does not define __ppc__ or __ppc64__, but
    does define __LITTLE_ENDIAN__.
    Hence remove the checks for __ppc__ and __ppc64__.
  - mips{,64}-linux-gnu{,abi64}-gcc does not define __BIG_ENDIAN__, but
    does define __MIPSEB__, so add a check for the latter,
  - m68k-linux-gnu-gcc does not define __BIG_ENDIAN__, but does define
    __mc68000__, so add a check for the latter,
  - hppa{,64}-linux-gnu-gcc defines __BIG_ENDIAN__, and thus should work
    out-of-the-box.

Untested due to lack of hardware.
