ia64: Document the typo that made it into the definition of MINSTKSZ

	(last two numbers got transposed).  Thanks to Arun Sharma for
	finding this.  New glibc's will have the value corrected, but
	we leave the kernel at the old (bogus) value to retain backwards-
	compatibility (and while a strange value, the old value works just
	fine).
