I'm confused about what this test is supposed to do.  It uses
"dg-do link" which means the compile (test for excess errors) will
fail if there is a reference to link_error.  There are two uses of
scan-tree-dump-times for the same string in the same file, so one
of those is guaranteed to fail.  It looks like the scans aren't
needed, and "dg-do link" is the thing that needs the xfail.
