Interesting, it would rehabilitate webengine for mingw.

I also note the known issue list says
"The toolchain uses Windows native TLS support, which doesn't work properly 
until Windows Vista."

It doesn't affect us, since we don't target anything older than W7, but it's 
good to know that it uses the native TLS support.

In any case, we don't need that full toolchain, since we don't need the LLVM 
tools. We can work with GNU binutils just fine with Clang.
