    rtld: Handle IFUNC symbols at non-PLT relocations
    
    An example of this is initializing a global variable with a pointer to
    ifunc.  This adds a symble type check and call resolver for STT_GNU_IFNC
    symbol types whien processing non-PLT relocations, but only after
    non-IFUNC relocations are done.  The two-phase processing is required
    since resolvers may reference other symbols which most be ready to use
    when resolver calls are done.
    
    This restructures reloc_non_plt() to call find_symdef() and handle IFUNC
    in a single place.
