The CPP below defines information about the compilation host. In
particular it defines the macro's:
- WITH_HOST_BYTE_ORDER The byte order of the host. Could
- be any of LITTLE_ENDIAN, BIG_ENDIAN
- or 0 (unknown). Those macro's also
- need to be defined.
+ HOST_BYTE_ORDER The byte order of the host. Could be BFD_ENDIAN_LITTLE
+ or BFD_ENDIAN_BIG.
