This feature is subtly broken when the linker is gold 2.26 or earlier. See the following bug for details: https://sourceware.org/bugzilla/show_bug.cgi?id=19002 Since the decision needs to be made at compilation time, we can not test the linker version. The flag is off by default on ELF targets, and on otherwise. llvm-svn: 302591
