	* sysdeps/unix/sysv/linux/ia64/setjmp.S: Define _GI___sigsetjmp
	and use it internally instead of __sigsetjmp.
	* sysdeps/ia64/fpu/s_frexpf.c (frexpf): Use _GI___libm_frexp_4f.
	* sysdeps/ia64/fpu/s_frexpl.c (frexpl): Use _GI___libm_frexp_4l.
	* sysdeps/ia64/fpu/libm_frexp4.S: Define _GI___libm_frexp_4.
	* sysdeps/ia64/fpu/libm_frexp4f.S: Define _GI___libm_frexp_4f.
	* sysdeps/ia64/fpu/libm_frexp4l.S: Define _GI___libm_frexp_4l.
	* sysdeps/ia64/fpu/s_frexp.c (frexp): Use _GI___libm_frexp_4.
	* sysdeps/ia64/fpu/libm_support.h: Declare _GI___libm_frexp_4,
	_GI___libm_frexp_4f, _GI___libm_frexp_4l.
	* sysdeps/ia64/fpu/bits/mathinline.h: New file.
	* sysdeps/unix/sysv/linux/ia64/__start_context.S: Use
	HIDDEN_JUMPTARGET for exit call.
	* sysdeps/unix/sysv/linux/ia64/clone2.S: Use HIDDEN_JUMPTARGET for
	_exit call.
	* sysdeps/ia64/bcopy.S: Use HIDDEN_JUMPTARGET for memmove call.
	* sysdeps/ia64/strcat.S: Use HIDDEN_JUMPTARGET for strlen and
	strcpy calls.
