This `markBroken` annotation was either added in error (by me), or the
package was removed from melpa-stable, but either way, it's no longer
in that package set, so remove the annotation.
This change sets an environment variable to ensure that Android Studio
uses the correct drivers to avoid any breackage when trying to run a
native application on a virtual device.
Without proper configuration `android-studio` would be unable to load
the drivers for the AVD and yield messages like this:
```

For further reference have a look at the following StackOverflow
message: https://stackoverflow.com/a/40790339
In anticipation of what I outline in #33599, I only simplify exactly those
`doCheck`s which are equal to `hostPlatform != buildPlatform`. I also stick a
comment next to them so I can grep for them later.
