Subject: [patch][gold] Fix PR11604

With the attached patch gold can, with the llvm plugin, pass the test in

http://llvm.org/releases/2.6/docs/LinkTimeOptimization.html

The last remaining issue was that the delayed layout would add back a
section the garbage collector decided was not needed.

I have ported the test to use the test plugin by checking in the original
.syms file but a .c file that reflects what LTO can do with it.
