This is not an invalid bug, but a failure of the GNU toolchain to correctly
mark "debug" shared objects.

In fact I just spoke with Nick Clifton about this in binutils, and it requires
we mark the "debug" shared objects to avoid this problem.

There is lots of tooling which needs to be updated to avoid loading "debug"
shared objects.

I'm reopening this bug and retitling.
