The new version has a change in behavior when using a custom platform:
* Old behavior: rules that don't require a toolchain used host_platform, no
matter what execution platforms are specified.
* New behavior: rules that don't require a toolchain use standard platform
resolution that starts with execution platforms.
As part of this change, we cannot use the "extra_exectution_platforms" flag
provided by the default bazelrc. I got rid of the default bazelrc file, and
made our custom .bazelrc as minimal as possible.
