Since cbee1bfb34 endian.h is unconditionally
used if available.
glibc has byte order defines with two leading underscores. OpenBSD
has private defines with a single leading underscore in machine/endian.h
and public defines in endian.h with no underscore.
The code under the endian.h block did not check if symbols were
defined before equating them so '#if __BYTE_ORDER == __LITTLE_ENDIAN'
would turn into '#if 0 == 0' which is always true.
Fixes: cbee1bfb34 ("meson/configure: detect endian.h instead of trying to guess when it's available")

This will allow it to be used as a drop in replacement for
_mesa_little_endian in a number of cases.
v2: - Always define PIPE_ARCH_LITTLE_ENDIAN and PIPE_ARCH_BIG_ENDIAN,
define the one that reflects the host system to 1 and the other to 0
- replace all uses of #ifdef, #ifndef, and #if defined() with #if
and #if ! with PIPE_ARCH_*_ENDIAN

_WIN32 is defined by basically all windows compilers (MSVC, ICL, MinGW),
wereas _MSC_VER is not defined by MinGW. Without this change MinGW falls
through and doesn't define PIPE_ARCH at all, and is caught by some extra
code in gallium.

If u_endian.h can't determine the endianess, the default behaviour in sha1.c
is to build for big-endian

This just ports the simpler endian detection bits, addrlib
sharing wants this outside gallium.
