bswap.h: add support for __BYTE_ORDER__
The __BYTE_ORDER__ define is provided by gcc (since ~v4.6), clang
(since ~v3.2) and icc (since ~16.0.3).
The __BYTE_ORDER and BYTE_ORDER macros are libc specific and are not
available on all supported platforms such as mingw.
Add support for the __BYTE_ORDER__ macro as a fallback.
