What we need to do is to remove the (use of) libgcc_s and not use libgcc_eh (static-libgcc) for Darwin > 10, since the unwinder is now in usr/lib/system/libunwind.dylib. Needs two chunks (1) move the content for TLS emulation somewhere else, since that's a reason to need libgcc_s (2) adjust the use of libgcc for Darwin > 10 to not include libgcc_eh for -static-libgcc. I have some patches for gcc-5 and 6 that do this, will forward-port them. I'm a little surprised that we need explicit -static-libstdc++ for gnat, the rest of the compiler already handles this?
