This isn't the same.  The handling of STV_PROTECTED is actually more
expensive than a normal symbol lookup because of the requirement of C
that function pointers are unique.  And function pointers in this case
would be the address of the PLT entry.  Look into elf/dl-lookup.c to
see what hoops we have to jump through.
