Exactly.

Ok, that's atleast a workaround, but I would like to understand what the
problem is exactly.

Indeed. Could you try sticking in a few debug echo lines, to figure out
what's going on?

 Sagaert> Meanwhile it might be a good idea to update the m4 package in buildroot to
 Sagaert> 1.4.13 instead of the current 1.4.9

Indeed. But you wrote something earlier about that not having any effect
on the above problem, right?
