Which tree are you testing with?

I've tested that this builds on top of Linus' current tree.

I had to create an aarch64-linux-gnu-clang wrapper, too. I'm not sure if
there's build system help to avoid needing that?

This appears to depend on how your toolchain was built as Nick mentioned in
an earlier message. I compiled clang from the unified LLVM git repo using
this configuration:

  $ make -G Ninja ../llvm-project/llvm \
	-DCMAKE_BUILD_TYPE=Release \
	-DENABLE_PIC=1 \
	-DLLVM_BINUTILS_INCDIR=/path/to/binutils-2.27/include \
	-DLLVM_TARGETS_TO_BUILD="X86;AArch64" && \
    ninja
