<pre>Building gn (<a href="http://gn.googlesource.com/">http://gn.googlesource.com/</a>) 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 <a href="https://gn.googlesource.com/gn">https://gn.googlesource.com/gn</a>
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 <a href="https://gn.googlesource.com/gn">https://gn.googlesource.com/gn</a>
cd gn
export CC=gcc
export CXX=g++
python build/gen.py --no-static-libstdc++
ninja -C out
out/gn_unittests
[works]</pre>
