 So, they are in our bug tracker? Great! We have about 1200 bugs open for
 Tor Browser and if you look carefully you'll see that the bugs get opened
 faster than we can fix them. Thus, you are very welcome to provide
 patches. We'd be happy to review them. This is after all a free software
 project and we welcome contributions.

 8.x :( There is an idea to bump LLVM to rc2 (if you wish), but build
 `llvm-strip` and `llvm-objcopy` separately from trunk.

 It *is* the one Mozilla uses for mingw-w64/clang builds and thus that is
 the one we care about right now as it's what is getting tested on
 Mozilla's infra.

 We don't build binutils, see the patch which is up for review. I am not
 strictly opposed to build those tools, as I said. It's just that it might
 be more work than it could be worth it.
