Agreed. I think looking at the host CPUs we support the only ones
that aren't guaranteed either big or little endian are (a) mips
and (b) ARM. ARM already identifies big-endian by a compile-time
check, and it seems likely that MIPS could too.
So, you're proposing just leaving the test as:
# if cross compiling, cannot launch a program, so make a static guess
case "$cpu" in
arm)
# ARM can be either way; ask the compiler which one we are

No, I'm proposing that you find out what the right check_define
for mips is and make mips|mips64 have a similar case to the arm
one. Google suggests the answer is __MIPSEB__; you can do a quick
check by firing up the mipsel/mips images from
http://people.debian.org/~aurel32/qemu/ under qemu :-)
-- PMM
Running
git grep "__MIPSEB__"
or
git grep "__MIPSEL__"
would be a quicker check :-))
