Series applied. To be honest, on the llvm patch, I was not sure about
forcing host-python3. Indeed, LLVM supports both Python 2 and Python 3,
and normally in such cases, we do something like this:

ifeq ($(BR2_PACKAGE_PYTHON3),y)
FOO_DEPENDENCIES += host-python3
else
FOO_DEPENDENCIES += host-python
endif

So that we re-use the same host-python as the one already being built
by Buildroot, if any. But I wasn't sure it was really useful in this
specific case, LLVM anyway takes ages to build.
