compat/bswap.h: detect endianness from XL C compiler macros
There is no /usr/include/endian.h equivalent on z/OS, but the compiler will define macros to indicate endianness on host and target hardware. This adds a test for these macros as a last resort for determining byte order. Signed-off-by: David Michael <fedora.dm0@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
