Unfortunately there seems to be no way around it. While I was working on
a fix, I decided to look into NutTcpAccept backlog and timeout first, in
the hope that this may lead to a different approach. It didn't.

For low memory systems we may optionally remove PASV support, so they
are not forced to spend RAM on an additional thread.

That's great. I do not have enough time right now, but sooner or later
I'll need a conformant FTP server for one specific product.
