That doesn't work (at least in build-tree testing), as gcc/testsuite/ is
not set up to look for header files in [target]/libgomp/:
[...]/source-gcc/gcc/testsuite/c-c++-common/goacc/kernels-acc-on-device.c:3:21:
fatal error: openacc.h: No such file or directory
compilation terminated.

Your two options are: if that's applicable/sufficient for what you intend
to test here, use __builtin_acc_on_device with a hard-coded acc_device_*,
or duplicate part of <openacc.h> as done for example in
gcc/testsuite/c-c++-common/goacc/acc_on_device-2.c.
