This also breaks all travis-ci builds.  I think it is critical to
refrain from using conditionals in test-suite stanzas for some time +
fix the "broken" release on Hackage.

Is there a way to make this issue more well-know.  Would a warning on
the upload page help?

@Richard FYI: Just uploading a new package won't solve this issue.
