Replace config-time define HOST_WORDS_BIGENDIAN
Replace a config-time define with a compile time condition define (compatible with clang and gcc) that must be declared prior to its usage. This avoids having a global configure time define, but also prevents from bad usage, if the config header wasn't included before. This can help to make some code independent from qemu too. gcc supports __BYTE_ORDER__ from about 4.6 and clang from 3.2.
