Comment (by mascguy):

 Replying to [comment:9 barracuda156]:
 > Besides, why do we even build test-suite here by default, when there is
 a tests variant? I suggest to add `-Dbuild-testsuite=false` into default
 config and replace it in tests.

 Ah, that was simply an oversight on our part. (Typically there's only one
 test-related option. But in this case, we have to disable two.)
