Uli's patch to fix this problem

The binding information printed for LD_DEBUG=bindings is incorrect when dlopen
is used.  This severely hinders people debugging problems with audit modules
and other problems.

Steps to Reproduce:
1.find program which uses dlopen with a handle returned by dlopen
2.use LD_DEBUG=bindings
3.

Actual results:
The 'from' map is reported to be the map with the definition

Expected results:
The from 'from' map should be reported.

Uli's patch for this problem is attached.  I haven't evaluated either the
problem or the patch.

I don't get any difference in the output of LD_DEBUG=bindings with or without
the patch.
