Fix pipe syscall on ia64

[Andreas Schwab]

On ia64 the pipe syscall returns two values instead of storing them
through a pointer.

Andreas.

2004-02-26  Andreas Schwab  <schwab at suse.de>

	* defs.h: Declare getrval2 also on IA64.

	* net.c (sys_pipe): For IA64 use the two return values.

	* syscall.c (getrval2): Implement for IA64.
