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.
