[testsuite] Skip gcc.dg/torture/20090618-1.c on IRIX (PR middle-end/47405)

[Rainer Orth]

As described in the PR, gcc.dg/torture/20090618-1.c fails on IRIX 5 and
6 due to undefined references to mempcpy, which doesn't exist in libc.
This might be a target bug.  Richard suggested to skip the test, which
this patch does.

Tested with the appropriate runtest invocations.  Applied to mainline
and 4.5 branch, ok for 4.6 branch, too?

Thanks.
