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.
