[PATCH] Fix ld.so trace mode

[Jakub Jelinek <jakub at redhat dot com>]

Hi!

LD_TRACE_LOADED_OBJECTS=1 always used to warn about undefined symbols if
LD_WARN=1 was specified at the same time, but current test does it the other
way around.
This is snippet from older rtld.c:
  /* LAZY is determined by the environment variable LD_WARN and
     LD_BIND_NOW if we trace the binary.  */
  if (__builtin_expect (mode, normal) == trace)
    *lazyp = _dl_verbose ? !bind_now : -1;
  else
    *lazyp = !bind_now;
ie. _dl_lazy was set to -1 if tracing and LD_WARN was not set.

	* elf/rtld.c (dl_main): If tracing, warn about undefined symbols if
	LD_WARN=1, not if LD_WARN is unset.
