[LLVMdev] mingw build problems

Another observation: GettingStarted.html still gives these
instructions for cross-compiling LLVM:

   1. Configure and build LLVM as a native compiler. You will need
just TableGen from that build.
          * If you have $LLVM_OBJ_ROOT=$LLVM_SRC_ROOT just execute
make -C utils/TableGen after configuring.
          * Otherwise you will need to monitor building process and
terminate it just after TableGen was built.
   2. Copy the TableGen binary to somewhere safe (out of your build tree).
   3. Configure LLVM to build with a cross-compiler. To do this,
supply the configure script with --build and --host options that are
different. The values of these options must be legal target triples
that your GCC compiler supports.
   4. Put the saved TableGen executable into the into
$LLVM_OBJ_ROOT/{BUILD_TYPE}/bin directory (e.g. into .../Release/bin
for a Release build).
   5. Build LLVM as usual.

... but all this messing about with tblgen seems to be completely
unnecessary now, presumably since this commit:
