Why is there a change to GTK steps? Did that change earlier?

It appears to be due to:
[GTK] Disable MSE build support on Debian and Ubuntu LTS bots
​https://bugs.webkit.org/show_bug.cgi?id=190581

[Michael Catanzaro]

The GTK/WPE change is wrong and unexpected. We were just trying to disable a build flag, not introduce a new build step. Are we sure this change was related to r237113? Anyway, I'm impressed that the test caught this problem.

CC Adrian. Adrian, the problem is the Ubuntu LTS bots have unexpectedly started running a JHBuild environment. They're supposed to be using system dependencies only, not JHBuild.

I came to this conclusion using git bisect. Checking build history, the step appearance lines up with when I restarted buildbot on October 15th (https://bugs.webkit.org/show_bug.cgi?id=190581#c7).

I'll just land the Win10/Win7 portion of my change.

[Michael Catanzaro]

Reported bug #191318 for the GTK problem.

I landed the Win10/Win7 test fixes in https://trac.webkit.org/changeset/237991/webkit
