Put external linkage symbols in .bss

Linux expects to see symbols with initializers in the .bss (or .sbss) sections.
I haven't been able to find an ABI document describing the correct behaviour,
so I'm experimenting on GCC.

The attached patch makes LLVM more closely match GCC's behaviour on PPC/Linux.
I don't think it breaks anything, and fixes programs which #include <iostream>
