It seems that the build system is completely unprepared to link to compiler-rt or libunwind when linking the shared library, and with -DLIBCXX_HAS_GCC_S_LIB=OFF, it fails due to a lot of missing symbols. I am going to revert this until we get the build system working completely.
Doesn't `-DLIBCXXABI_USE_LLVM_UNWINDER=ON` make it possible to build without `libgcc_s`? Or is this something else?
