I tried building Sage from source on the new Ubuntu 18.04 in a clean Docker container with just a handful of basic packages installed, principally gcc 7. It was unable to build ecm-7.0.4.p1 which is included in 8.2rc1. Here is what seems to be the core of the error message:

I will try building on an older Mac Pro and see if the failure is processor dependent, but I have successfully built 8.2rc1 on the same machine in a 16.04 Docker container.
