GOLD/DWP: exit without segfault if the binary is not built with debug fission.
dwp segfaults when trying to get .dwp file from a binary built without debug fission. This patch fixes that. upstream thread is https://sourceware.org/ml/binutils/2016-05/msg00204.html BUG=None TEST=dwp still works with files built with debug fission and dwp does not segfault on files that are not built with debug fission.
