The OpenMP Validation&Verification test [https://github.com/OpenMP-Validation-and-Verification/OpenMP_VV/blob/master/tests/5.2/declare_mapper/test_declare_mapper_present.c] stopped working after 1fbf33cd4039d7fe97a20d8885c0f26fc441cf5e. The option `LIBOMPTARGET_TREAT_ATTACH_AUTO_AS_ALWAYS=0` does not fix it either.
1fbf33cd4039d7fe97a20d8885c0f26fc441cf5e^ (before #153683):
```
test_declare_mapper_present.c.o: PASS. exit code: 0
test_declare_mapper_present.c.o:
