Hi Ben,

Indeed, I'm doing the release on an old and stable Linux, to mimic
what people had before the ABI move.

I had a few libunwind/libc++ issues on AArch64, but they were related
to GNU problems, so the way I build now (not for the release) is to
get no libc++/unwind on stage 1 and then use stage1's Clang to build
libunwind:

http://buildmaster.tcwglab.linaro.org/builders/clang-cmake-aarch64-prototype

Builds fine, but there are some errors in stage2's test.

Maybe your version of GAS doesn't support FP/LR? Mine is binutils
2.25, gcc 4.9.2.
