I have tracked it down to the real reason. The revisions 139934-139937 has changed the order in which configure chooses a compiler. Clang is checked first, then llvm-gcc, and then gcc.
I can see the reason for this change. However, in this particular case it has broken the build because Ubuntu includes clang 2.8 which doesn't know where includes are. I have removed clang from the host to force gcc to be chosen, which is what is intended for this builder. The buildslave will be back on-line shortly. Thanks Galina.
