[lld] r318937 - Make a test stricter.

New Revision: 318937

URL: http://llvm.org/viewvc/llvm-project?rev=318937&view=rev
Log:
Make a test stricter.

It now has a DT_NEEDED that could be removed by --gc-sections and one
that cannot. Without this all tests would pass if --gc-sections just
removed all DT_NEEDED.
