Well, it's built if you configure GDB with --enable-targets holding
aarch64-linux-gnu, and if you don't use that configure option then you
can't cross-debug ARM cores on non-ARM systems.

If you're suggesting that it should be possible to cross-debug for ARM
without that sim, I can't speak to that.

Cheers!
