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:
"arm64: extable: sort the exception table at build time"
