Provide way to disable transition to default platform #2792
Description
rules_apple has a default transition to a mac osx platform. In our case, I believe it is transitioning to the same platform as our normal OSX build, but this is a pain as we want to skip targets on other platforms if they aren't compatible.
It seems that transitioning makes target_compatible_with take no effect, the target doesn't get filtered out, and then bazel raises a confusing error (in this case about there not being a toolchain to compile for OSX with host platform linux-x64), rather than skipping the target. I want the target to be filtered out by bazel's normal handling of targets incompatible with the target platform, to make things like bazel build --nobuild //... and bazel test //... work on every platform target for a multi-architecture codebase that has some parts that are OSX-specific.
