[PATCH] D25413: [libcxx] Use libunwind instead of libgcc_s if libcxxabi uses it

[Michał Górny via llvm-commits]

This is not that simple. Remember that libgcc_s serves both as unwinder and compiler runtime. Since libcxx is linked with -nodefaultlibs, including gcc_s is necessary to fulfill dependency on automatically generated runtime calls (__udiv* stuff, for example). I'm working on fixing that properly but it is stalled on https://reviews.llvm.org/D25338.

Also, your patch is based on outdated code. Please update your repository before submitting patches.
