Revision r167779 <http://trac.webkit.org/changeset/167779> broke the GTK build.
Check the output here: http://build.webkit.org/builders/GTK%20Linux%2064-bit%20Release/builds/46809
ninja: error: '../../Source/WebInspectorUI/UserInterface/External/CodeMirror/less.js', needed by 'DerivedSources/webkit2gtk/InspectorGResourceBundle.xml', missing and no known rule to make it
That file is not explicitly listed in any makefile, I bet it's the stupid cmake cache causing this, let me try a clean build.
It was failing (again? also?) on GTK+ Linux 64-bit Debug and I removed the WebKitBuild/Debug folder in the bot to trigger a clean build on next commit. Now it seems to be building fine in that bot.
GTK Linux 32 bit Release and GTK Linux ARM Release are failing, though, but I don't have access to those bots.

Seems that you are right.
After forcing a clean build all GTK bots are working back: http://build.webkit.org/waterfall?category=GTK
Closing this as fixed.
