libgomp nvptx plugin: Remove '--with-cuda-driver=[...]' etc. configuration option
That means, exposing to the user only the '--without-cuda-driver' behavior:
including the GCC-shipped 'include/cuda/cuda.h' (not system <cuda.h>), and
'dlopen'ing the CUDA Driver library (not linking it).
For development purposes, the libgomp nvptx plugin developer may still manually
override that, to get the previous '--with-cuda-driver' behavior.
libgomp/
* plugin/Makefrag.am: Evaluate 'if PLUGIN_NVPTX_DYNAMIC' to true.
* plugin/configfrag.ac (--with-cuda-driver)
(--with-cuda-driver-include, --with-cuda-driver-lib)
(CUDA_DRIVER_INCLUDE, CUDA_DRIVER_LIB, PLUGIN_NVPTX_CPPFLAGS)
(PLUGIN_NVPTX_LDFLAGS, PLUGIN_NVPTX_LIBS, PLUGIN_NVPTX_DYNAMIC):
Remove.
* testsuite/libgomp-test-support.exp.in (cuda_driver_include)
(cuda_driver_lib): Remove.
* testsuite/lib/libgomp.exp (libgomp_init): Don't consider these.
* Makefile.in: Regenerate.
* configure: Likewise.
* testsuite/Makefile.in: Likewise.
