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.
