Thanks a lot for this hint.

I'm definitely not motivated to do some severe debugging, sorry.

It would be a quite safe bet to assume that there are zero users for
this tool on armel. So if armel porters want to do some work on the
issue I do not want to stop them - may be even building it on a more
performant machine might help since the very same code has build before.
If not I'll ask ftpmaster for removal of this architecture.
Kind regards
Andreas.
