[PATCH] D40326: Fix static link on debian

[Rafael Avila de Espindola via llvm-commits]

In any case. Desirable or not that is what the libstdc++ implementation
is and we have to live with it.

We have to do something like this in CMAKE or just report an error
saying that we don't support static linking when using libstdc++.

Cheers,
Rafael
