We should not use double-underscore (or underscore-capital) symbols in
arbitrary user space code, and these include files are specifically
used for user space compilation. Furthermore, the indirection is
completely unnecessary in this case.
Also, reorder the littleendian put macros to allow the compiler to
generate better code on some architectures (stores in sequence.)
