[Rafael Espindola via llvm-commits]

New Revision: 319217

URL: http://llvm.org/viewvc/llvm-project?rev=319217&view=rev
Log:
Bring r319051 back.

It had been reverted because it depended on r319008 which has been
recommitted.

Original message:

Add a missing test.

We were not testing that we correctly handled a .o with a weak symbol
after a .so.
