[patch] IA64: Uninitialized pointer in _dl_static_init

[Maciej W. Rozycki]

Hello,

 While testing variable page support for MIPS I've discovered
_dl_lookup_symbol() triggers a segmentation fault if passed an
uninitialized pointer as ref.  This happens because ref is used for symbol
lookup as well unless NULL.  Here is a fix.

	* sysdeps/unix/sysv/linux/ia64/dl-static.c (_dl_static_init): 
	Initialize ref before passing it to _dl_lookup_symbol().

 Please apply.

  Maciej
