aosp_x86_arm builds have overriding commands

This product has warnings about overriding build commands, which means
that there are multiple instructions on how to build a file, and we've
just picked one of them. Which one we pick is usually stable, but it can
change.

Bug: 77611511
Test: turn default to false, aosp_x86_arm still uses a warning
