Konstantin Belousov 14c3564759 IFUNC symbol type shall be processed for non-PLT relocations,
e.g. when a global variable is initialized with a pointer to ifunc.
Add symbol type check and call resolver for STT_GNU_IFUNC symbol types
when processing non-PLT relocations, but only after non-IFUNC
relocations are done.  The two-phase proceessing is required since
resolvers may reference other symbols, which must be ready to use when
resolver calls are done.

Restructure reloc_non_plt() on x86 to call find_symdef() and handle
IFUNC in single place.

For non-x86 reloc_non_plt(), check for call for IFUNC relocation and
do nothing, to avoid processing relocs twice.
