I have solved the issue with this change to buildroot:

The origin of the patch is in
http://www.bitshrine.org/gpp_info/DirectFB-0.9.24-relink.patch.html
but that was outdated and I had to do it manually (not a big
effort indeed).

Not sure that it's a real solution or that it has no side effects,
but it worked for me.
