Jakub Jelinek 79e3f7d54b libgomp: Add openacc_{cuda,cublas,cudart} effective targets and use them in openacc testsuite
When gcc is configured for nvptx offloading with --without-cuda-driver
and full CUDA isn't installed, many libgomp.oacc-*/* tests fail,
some of them because cuda.h header can't be found, others because
the tests can't be linked against -lcuda, -lcudart or -lcublas.
I usually only have akmod-nvidia and xorg-x11-drv-nvidia-cuda rpms
installed, so libcuda.so.1 can be dlopened and the offloading works,
but linking against those libraries isn't possible nor are the
headers around (for the plugin itself there is the fallback
libgomp/plugin/cuda/cuda.h).

The following patch adds 3 new effective targets and uses them in tests that
needs those.
