/* Check OMP_TARGET_OFFLOAD on systems with non-host devices but no executable
code due to -foffload=disable.
Note: While one might expect that -foffload=disable implies no non-host
devices, libgomp actually detects the devices and only fails when trying to
run as no executable code is availale for that device.
(Without MANDATORY it simply uses host fallback, which should usually be fine
but might have issues in corner cases.)
We have default-device-var = 0 (default but also explicitly set), which will
fail at runtime. For -foffload=disable without non-host devices, see
target-50.c testcase. */
