Be more strict on when we produce an undefined reference. In gas a file with just .type foo,@object will produce an undefined reference to foo. On the other hand, a file with just .weakref bar, foo will not. It is somewhat hard to support both in MC since both statements should create the symbols. It should be possible if we really need to by adding to the flags, but hopefully that is not necessary. With this patch we do not produce a undefined reference in any of those cases. The assembly file needs an actual use for the undefined reference to be present. This is in preparation for a patch implementing .weakref. llvm-svn: 117735
