I haven't looked at this but I think this is typical of the plabel
setup for lazy binding.  In GCC under linux, we need to call into
the dynamic linker to force resolution of the function when doing
function pointer comparisons.  This is the infamous __cffc routine.
I think gdb will have similar issues when trying to set a break
in a shared library.
