<p class="MsoNormal">My apologies. There were a couple of problems with my build environment. First, there was an old config cache messing up the configuration step. Also, the gcc being used was v7, not v8. Both versions are present but v7 is the default.
After fixing those problems and disabling gss I’m left with a single failure which Shaun referenced below (commit 7674f2c976744c38fd761518db92e01b22de2fbb) :<o:p></o:p></p>
