Comment (by eschnett):

 GCC says:

        -rdynamic
            Pass the flag -export-dynamic to the ELF linker, on targets
 that
            support it. This instructs the linker to add all symbols, not
 only
            used ones, to the dynamic symbol table. This option is needed
 for
            some uses of "dlopen" or to allow obtaining backtraces from
 within
            a program.

 This seems like a safe thing to do. Note that we override many defaults in
 the SimFactory, so I would begin by adding it to SimFactory's option lists
 on the machines that we often use.
