Update.
* elf/Versions (ld): Export _dl_out_of_memory for GLIBC_2.2.
* dlfcn/dlerror.c (dlerror): Don't free the error string if it is the
report that we are out of memory.
* elf/dl-deps.c (_dl_map_object_deps): Likewise.
* elf/dl-libc.c (dlerror_run): Likewise.
* elf/dl-open.c (_dl_open): Likewise.
* elf/rtld.c (dl_main): Likewise.
* elf/dl-error.c: Define _dl_out_of_memory.
(_dl_signal_error): Return _dl_signal_error if we cannot duplicate
the error string.
* sysdeps/generic/ldsodefs.h: Declare _dl_out_of_memory.
* dlfcn/dlerror.c (free_key_mem): Also free error string.
* iconv/loop.c: Fix comment.
