Fix spurious failures in foll-{v,}fork.exp


The patterns in foll-fork.exp and foll-vfork.exp don't match reality on
ia64.

Andreas.

2008-11-20  Andreas Schwab  <schwab@suse.de>

	* gdb.base/foll-fork.exp (catch_fork_child_follow): Fix patterns
	matching syscall entry point.
	* gdb.base/foll-vfork.exp (tcatch_vfork_then_parent_follow)
	(tcatch_vfork_then_child_follow): Likewise.
