Hello Jan-Ralph,

given your reasonable current host Linux I expect an incompatibility
of Rump with your recent host tool chain. I did not try this myself
but the following error seems to hint that.

You may install an older (version 4?) Ubuntu GCC, generate appropriate
symbolic links for gcc etc. in a distinct directory, add that
directory to the front of your PATH environment variable, and rebuild
