Did you try the latest version?
And/Or the latest development version?
(I know absoltly nothing about qemu)

You can skip tests yes... but then no one knows if your perl really  
works or if it is broken (maybe in subtle ways).
The tests are there for a reason.

Your third option is to find out what syscall 338 is and see if it can  
be added to qemu.

Your foruth option is to try to silence the error. Some test expect  
the output on STDERR in a particular order andon particular lines. If  
there is another error in that output the test fails.

Define fine?
How did you test it?
The only way to make sure it runs fine is to run make test (and even  
then you can't be 100% sure)
