My wild guess tells me that the rtld_bind_lock gets held recursively
when resolving filtered symbol.
The attached band-aid patch supports the guess.

I have the world/kernel as of r234038 and have difficulty to launch XFce's
xfdesktop-settings (w/ im-scim.so which loads libstdc++), where every threads
of xfdesktop-settings stuck into either "urdlck" or "uwrlck" states.

I have to admit that the attached patch is something like 3-minute-hacking
quality, but it at least avoids the stall.
