Comment (by gk):
Okay, here is my plan. clang 3.8.0 requires GCC 4.8 which our current host
system does not have. So, we actually have two options to fix that:
1) We build a recent enough GCC (or clang for that matter) first and then
build our clang. That could be tricky and time-consuming given a non-
standard location of that GCC and its related libs
(https://btorpey.github.io/blog/2015/01/02/building-clang/ has a fancy
tutorial for that).
2) We could just use Debian Jessie (which comes with GCC 4.9) instead of
Debian Wheezy. I tried that today and it worked as expected.
I think I'll do 2) and spend a bit time on getting rid of the old macOS
toolchain which allows us to get rid of i386 VMs in the macOS build
process. I am almost done with a respective patch for #10369 which is the
bulk of that work. Then we only need to adapt the PT descriptor (i.e. we
need to switch to using clang instead of GCC).
