Hi it is me again.
This is the latest ldso patch. the NEW weak symbol handling works now
with a little special handling in _dl_find_hash(). You get to chose
if you want the new or old handling :)
There was 2 missing _dl_check_if_named_library_is_loaded() calls in _dlopen().
I then disabled the _dl_check_if_named_library_is_loaded() in dl-elf.c since
it is rendundant.
Question, why does some _dl_linux_resolver(), like i386, have 2 calls
to _dl_find_hash()? I think that is wrong, isn't it?
I really hope you can check this out soon ...
