Properly mark mmap_ent as global

It currently happens to work fine using cg_llvm as the global_asm!() ends up in the same cgu as the use of this global. There is no guarantee that this will always be the case and in fact in case of cg_clif this happens to not be the case, thus causing a linker error.
