A commit in the last 12 hours breaks building. Configure options (grep configure) and error message (at the end of the log) are here: https://launchpadlibrarian.net/196047722/buildlog_ubuntu-utopic-i386.mesa_10.5~git1501281930.3b7747~gd~u_FAILEDTOBUILD.txt.gz
This patch should fix it. Please let me know if it does: http://lists.freedesktop.org/archives/mesa-dev/2015-January/075282.html
I cannot test (posting from a phone) until some days. But if you commit it I can check if it passes the next automatically scheduled build.
Just pushed the fix to master and it seems to fix it for other people. I'm closing this bug. Reopen if it's still a problem.
