Can you reproduce with 18.2.4?
I just tested to build mesa 18.2.4. The executive summary :) seems to be the following: 1. mesa-18.0.0_rc4 was failing because of LTO. rc3 was fine 2. mesa-18.2.4 fails with LTO as well but in a different way (see below) 3. Both compiles fine if I turn off LTO.

Thanks. Mesa is known not to build with LTO -- bug 641808.
