It turns out that there is another function with almost identical loop. 
This time, in 'update_solib_list' gdb would do the same: in one 
iteration it frees an objfile, in another tries to free it again.

The attached patch supersedes the first one and extracts the logic for 
determining duplicates into a function, then uses the function.

Still no regressions.


Comments appreciated.
