I know that gcc defines some preprocessor macros that let the
preprocessor generate different code for different architectures (I'm
using some of them) but I can't seem to find any that tell me about
either data format (big or little endian) or invocation options. Does
anyone know of anything I can use.

#include <endian.h>

#if __BYTE_ORDER == __LITTLE_ENDIAN
...
#elif __BYTE_ORDER == __BIG_ENDIAN
...
#endif

bits/endian.h is where __BYTE_ORDER is ultimately defined.
