Thanks for that workaround. What I've been doing is copying
/lib/libgcc_s.so.1 over LLVM's copy and rebuilding xgcc.

A long-term fix for this would be nice.

Why does llvm-gcc build its own libgcc_s.so? Would we have the same
problem if we tried to build FSF GCC 4.01, or is this problem LLVM-specific?
