PATCH: Handle undefined symbol in DSO from DT_NEEDED

glibc 2.2.3 changes atexit from default to hidden. DSOs with
unversioned references to atexit fail to link if they are loaded
in via a DT_NEEDED entry. This patch makes it non-fatal. I will
check it in if I don't hear any objections by Thursday.

	* elflink.h (elf_link_output_extsym): Undefined symbol in DSO
	loaded in via a DT_NEEDED entry is not fatal.
