Also, with my last push (adjusting the template instantiation patch to
!isWindowsCygwinEnvironment) I can again use llvm-mingw wrappers of the
installed Cygwin clang/lld to cross-compile llvm for i686-w64-mingw32.

 git clone https://github.com/mstorsjo/llvm-mingw.git
 cd llvm-mingw
 ./build-all.sh --host-clang /opt/llvm-mingw
 cd mingw-w64; git clean -dxxf .
 cd ../llvm-project; git clean -dxxf .
 patch -p1 -i .../llvm/0004-LLVM-Cygwin-Fix-Signals*.patch
 patch -p1 -i .../llvm/0006-LLVM-Cygwin-Define-_GNU_SOURCE-*.patch
 cd ..
 ./build-cross-tools.sh /opt/llvm-mingw i686-prefix i686

(it should work for any of the 4 arches i686 x86_64 armv7 aarch64)
