I tightened the test checking - enabled them during build and made them 
more verbose (and explicitly passed environment variable "srcdata" which 
might have previously failed).

Those changed was finalized and released today as 5.8.0-2, and I hope it 
can shed some light on what more detailed fails when it does.

To my surprise, the armhf failures are evidently no longer persistent 
even _before_ this latest release.  I therefore relax severity of this 
bug.


Thanks for the report, Graham,

 - Jonas
