improve host/cross target checking #136767

onur-ozkan · 2025-02-09T09:07:00Z

Using an invalid equality operator on builder.config.build !=/== can be hard to detect in reviews (which is quite dangerous). Replaced them with is_host_target, which is much clearer as it explicitly states what it does.
