I see where you go, but I disagree. IMHO symbols in the ld-elf.so.1 
should be searched even if there is no matching weak symbol found in 
other libraries. Technically, nothing says that the libc should have 
those weak symbols for dlopen and friends and also application can only 
be linked to ld-elf.so.1, not libc at all, and still dlsym("dlopen") 
should work.
