And now what I hope will help:
Somebody else had a similar error in February in mesa-17.3.3, and Pierre thought it was probably caused by reinstalling gcc in BLFS. http://lists.linuxfromscratch.org/pipermail/blfs-dev/2018-February/033975.html He suggested running (as root, I've changed the version to match your gcc) : /usr/libexec/gcc/x86_64-pc-linux-gnu/7.2.0/install-tools/mkheaders OTOH, if you haven't reinstalled gcc this probably won't be relevant and I'm not sure exactly what it would do to your modified headers. ĸen -- Before the universe began, there was a sound.
