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

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
