bug fix for ia64/dl-fptr.c

[David Mosberger]

The ia64 version of dl-fptr.c has a bug in that it incorrectly assumes
that the "local" variable will be within a 22-bit offset of gp.  The
fix is to use "movl" instead so that "local" can be anywhere in the
64-bit address space.

Thanks to Asit Mallick for reporting this bug.

	* sysdeps/ia64/dl-fptr.c (make_fdesc): Load address of "local" via
	a 64-bit gp-relative address to enable binaries with large data
	sections.
