Rid libdummy.a from lto.exp
libdummy.a is used to make run_cc_link_tests compile objects and
archive them. libdummy.a isn't used. What we're really doing is
preventing a final link. So do that directly.
* lib/ld-lib.exp (run_ld_link_tests): Stop after assembling objects
if binfile is empty.
(run_ld_link_exec_tests, run_cc_link_tests): Likewise. Tidy
status checks.
* ld-plugin/lto.exp: Don't use libdummy.a trick to compile objects.
Instead use an empty output file.
