Replace hard-coded offsets into struct sigcontext with generated file.
	* sysdeps/unix/sysv/linux/ia64/sigcontext-offsets.sym: New file.
	* sysdeps/unix/sysv/linux/ia64/Makefile
	[$(subdir) = stdlib] (gen-as-const-headers): Add it.
	* sysdeps/unix/sysv/linux/ia64/ucontext_i.h: Include it instead of
	defining SC_* macros here.
