I am not sure. By "work right", I mean you can compare "&function"
taken inside and outside of DSO. That is one reason STV_PROTECTED is
treated almost exactly like STV_DEFAULT. The static linker does
very little and the dynamic linker does the most.

BTW, glibc failed to "make check" in elf on ia64 because of it. Maybe
we can add

	case STV_PROTECTED:
	  if (info->shared)
	    return false;

But I am not very so sure it is 100% correct.
