UAPI: fix endianness conditionals in M32R's asm/stat.h
In the UAPI header files, __BIG_ENDIAN and __LITTLE_ENDIAN must be
compared against __BYTE_ORDER in preprocessor conditionals where these are
exposed to userspace (that is they're not inside __KERNEL__ conditionals).
However, in the main kernel the norm is to check for
"defined(__XXX_ENDIAN)" rather than comparing against __BYTE_ORDER and
this has incorrectly leaked into the userspace headers.
The definition of struct stat64 in M32R's asm/stat.h is wrong in this way.
Note that userspace will likely interpret the field order incorrectly as
the big-endian variant on little-endian machines - depending on header
inclusion order.
[!!!] NOTE [!!!] This patch may adversely change the userspace API. It might
be better to fix the ordering of st_blocks and __pad4 in struct stat64.
