take byte order from gcc if gcc has defined it
this only works with gcc 4.6 and later, but it allows us to support non-default endianness on archs like arm, mips, ppc, etc. that can do both without having separate header sets for both variants, and it saves one #include even on fixed-endianness archs like x86.
