The new gcc.dg/torture/pr47917.c test currently fails the execution test
on IRIX 6.5. To get a C99-conformant snprintf, one needs to include
<stdio.h> with _XOPEN_SOURCE defined as 500. The following patch does
this.
Tested with the appropriate runtest invocations on mips-sgi-irix6.5 and
i386-pc-solaris2.11.
Ok for mainline?

* gcc.dg/torture/pr47917.c: Add -D_XOPEN_SOURCE=500 to dg-options
for mips-sgi-irix6.5.
Replace snprintf prototype by <stdio.h>.
