search for: _urc_ok

Hi Logan, So, I just realised clang 3.8 comes with an unwind.h which doesn't have _URC_OK defined (introduced in r262178, just after 3.8 split). But on that commit, the personality routine depends on it for EHABI calls, which is defined by default on ARM environments. The end result is that I can only use Clang 3.9+ to compile libunwind 3.9+. http://buildmaster.tcwglab.linaro.org/bui...

Hello, on the problems cross-building compiler-rt: Tried to follow https://llvm.org/docs/HowToCrossCompileBuiltinsOnArm.html which lead to this cmake: cmake -G "Ninja" ../llvm/projects/compiler-rt/ -DCOMPILER_RT_BUILD_BUILTINS=ON -DCOMPILER_RT_BUILD_SANITIZERS=OFF -DCOMPILER_RT_BUILD_XRAY=OFF -DCOMPILER_RT_BUILD_LIBFUZZER=OFF -DCOMPILER_RT_BUILD_PROFILE=OFF
