Comment (by trommler):

 Replying to [comment:38 pkubaj]:
 > Log has ./configure, gmake and gmake binary-dist steps.
 The cross compiler on amd64 is gcc 6.4 while on powerpc64 it is gcc 8.
 Could you make sure
 both versions agree? I want to get as many potential sources of trouble
 out of the equation.
