The compile & test on line 47 is failing on z/OS with the following message:
```
clang: error: cannot determine amdgcn architecture: No AMD GPU detected in the system; consider passing it via '--offload-arch'; environment variable CLANG_TOOLCHAIN_PROGRAM_TIMEOUT specifies the tool timeout (integer secs, <=0 is infinite)
```
I'm not sure if there is a way to fix this (eg. wildcard in the expected output or a compiler option).  If there isn't can you add:
```
UNSUPPORTED: system-zos
```
