	Collect2 generated the shared library.

	According to an analysis in a related bug report, it appears that
GCC's assumption about the sorting of FDEs is getting confused by the
address ranges of shared libraries used by AIX.  The duplicate symbols
cause FDEs for the same symbol to appear in multiple shared libraries.
