Fixup byte order handling. Not all architectures define __BIG_ENDIAN__ so i.e.

on big endian mips the code is compiled as little-endian and the wrong half of
the 64-bit point value is examined to check for NaN, etc.  This bug also broke
fpclassify(), isfinite(), isnormal(), isinf(), finite(), and signbit().
