Building gn (http://gn.googlesource.com/) with clang results in a crash on
startup (Illegal Instruction) on armv7hnl.
It works on any other architecture and on armv7hnl with gcc instead of clang.

To reproduce (no reduced test case yet):

git clone https://gn.googlesource.com/gn
cd gn
export CC=clang
export CXX=clang++
python build/gen.py --no-static-libstdc++
ninja -C out
out/gn_unittests

[Illegal Instruction on armv7hnl, success everywhere else]

git clone https://gn.googlesource.com/gn
cd gn
export CC=gcc
export CXX=g++
python build/gen.py --no-static-libstdc++
ninja -C out
out/gn_unittests

[works]
