microblaze: extable: sort the exception table at build time
Sort the exception table at build-time rather than during boot. Microblaze is the same case as AARCH64 that's why EM_MICROBLAZE conditional check was added to allow cross-compilation on machines which are not running the latest libc-dev. Inspired by AARCH64 commit adace89562c7 ("arm64: extable: sort the exception table at build time").
