Darwin, testsuite : Prune 'object file not found for object'.

This is not a GCC problem, but a fault in the static linker where,
when a source file is used multiple times, with conditional compilation
the source file is only referenced by the linker for the first object.
Then, when dsymutil tries to find the source file for next object based
off that source there is no record for it.

gcc/testsuite/ChangeLog:

	* lib/prune.exp: Prune useless output caused by a linker bug.
