Test suite fail on Ubuntu 18.04

On a Ubuntu 18.04 system with libgccjit-7-dev installed the test suite fails:

...

Thank you for the report.

This appears to be caused by a packaging issue Ubuntu has inherited from Debian: libgccjit0 doesn't work without a matching version of gcc package installed. Ubuntu 18.04 ships libgccjit0 version 8.2.0, which needs gcc-8, but by default Ubuntu only installs gcc-7.
