[19/19] tests/functional: Add microblaze cross-endianness tests

Commit Message

Philippe Mathieu-Daudé Nov. 5, 2024, 1:04 p.m. UTC

Copy/paste the current tests, but call the opposite endianness
machines, testing:
- petalogix-s3adsp1800-le machine (little-endian CPU) on the
  qemu-system-microblaze binary (big-endian)
- petalogix-s3adsp1800-be machine (big-endian CPU) on the
  qemu-system-microblazeel binary (little-endian).

Clever refactor left for later
