* dlfcn/dlfcn.h: Pretty print dladdr declaraction.

	* elf/rtld.c (process_envvars): Recognize LD_DYNAMIC_WEAK.
	(_dl_dynamic_weak): New variable.
	* elf/dl-support.c: Likewise.
	* sysdeps/generic/ldsodefs.h: Declare _dl_dynamic_weak.
	* elf/do-lookup.h: If we find a weak definition treat it like a
	normal symbol unless _dl_dynamic_weak is nonzero.  In the latter
	case treat it like before.
