++  [changes brought forward from 17.2.2-1+rpi1 by Peter Michael Green <plugwash@raspbian.org> at Tue, 17 Oct 2017 23:01:04 +0000]
 +  * Add more debug output to configure.ac
 +  * Hardcode llvm soname, the code for auto-determining it seems to be misbehaving.
 +  * Add build conflicts on libunwind-dev, having it installed currently breaks the build.
