Comment:

 Okay, I have something for review. The unsquashed version is available in
 `bug_28716_v2` (https://gitweb.torproject.org/user/gk/tor-browser-
 build.git/log/?h=bug_28716_v2), the squashed one in
 `bug_28716_v3_squashed` (https://gitweb.torproject.org/user/gk/tor-
 browser-
 build.git/commit/?h=bug_28716_v3_squashed&id=039f08f5cae5303c5b472a5203096799f0fc6c85).
 See the commit message of the latter for what I did (mainly following
 https://hg.mozilla.org/releases/mozilla-
 esr60/file/a578196b1fe0/taskcluster/scripts/misc/build-clang-trunk-
 mingw.sh plus a bunch of deviations (I hope I got all of the important
 ones)).

 I am still testing the toolchain(s), but so far the result looks
 promising: I was able to compile the 64bit Firefox part with a .mozconfig
 file that resembles the one we ship (I only had to omit the sandbox
 compilation, as that one is broken right now, which we need to
 investigate).
