I created a brand new virtual machine running Ubuntu 18.04 (x86_64), installed the prereqs as listed here:  https://gcc.gnu.org/install/prerequisites.html, created the repo following the "Getting Started - Read Only" instructions listed here: https://gcc.gnu.org/wiki/GitMirror, then ran these commands from my build folder.

That doesn't seem too bad.

Which results are you looking at?
Two failures sounds very low, it's probably not running the guality
tests which usually fail.
