The manual for -fnon-call-exceptions says:
"Note that this requires platform-specific runtime support that does not exist everywhere."
I don't know exactly what that means, so the test only runs on targets
where I know it works.

It's not supposed to be an exhaustive list of targets where it's
supported. As I said, it's a conservative list.
It could run on more targets, but there might not be much benefit as
long as the test runs on some targets that get tested often.
