Update.
* include/link.h (struct link_map): Add l_lookup_cache element. * elf/dl-reloc.c (RESOLVE): Add symbol caching here. (RESOLVE_MAP): Likewise. (_dl_relocate_object): Remove cache initialization. * elf/dl-lookup.c: Rip out cache handling code. * sysdeps/generic/ldsodefs.h: Remove lookup_cache struct and variable declarations. * elf/dl-lookup.c (_dl_lookup_symbol): Reorder some conditions and remove some __builtin_expect. (_dl_lookup_versioned_symbol): Likewise. R_386_RELATIVE handling for ld.so startup. Reduce RTLD_BOOTSTRAP case to almost no code.
