micropython on big-endian systems

[jepler]

Because I was curious, I built micropython for the ibm s390x CPU architecture, which is big-endian LP64 Linux, and then ran the testsuite (this uses qemu under the hood). Result: The tests passed, except for stress_aes which was a timeout.

I had to use standard linking but that was also true of trivial programs and may result from some kind of misconfiguration of either the compiler or qemu binfmt support in debian trixie.

$ make VARIANT=standard CROSS_COMPILE=s390x-linux-gnu- LDFLAGS_EXTRA=-static -j$(nproc)  MICROPY_PY_FFI=0  test

I also ran the basic tests via mpy-cross, and that worked as well.

Nothing interesting to see here, just a success.

Congratulation! You passed the test, to develop more code for Micropython!
