I do not compile on my target (and have no need for doing so) so for me 
it is good enough to compile the test app "outside" the suite and run 
manually on the target. Everyone else can use it within the suite to 
test their own environment.

If there are no other objections to the patch, I propose to commit it. 
Any volunteers?
TIA,
Mikael
