How did you try it?  The gnu linker by default does not export
symbols from applications if they are not referred to by some
shared library they're linked against.

So a valid test would require that you either link the application
against a second library that referenced __dso_handle, or that
you use --export-dynamic when linking the application.

What's needed is some of the ELF extensions recently approved by
the committee but not yet implemented in gnu ld (or anywhere else
for that matter).  I'm thinking here of STV_PROTECTED.
