[BUG] `aztec compile` fails with "AVM Transpiler is not enabled" on linux/arm64

[jasonxh]

What are you trying to do?

With the "dockerless" CLI from v4, aztec compile gives this error when trying to compile any contract on linux/arm64:

AVM Transpiler is not enabled. Please enable it to use bb aztec_process

Additional Context

This seems to be where the error came from, indicating the linux/arm64 bb binary isn't compiled with ENABLE_AVM_TRANSPILER flag for some reason.

This has been fixed in #20814, it will work on the next release. Thanks for reporting!
