[PATCH 4/4] OpenMP 4.0 offloading to Intel MIC: non-fallback testing.

libgomp/
	* Makefile.in: Regenerate.
	* configure: Regenerate.
	* configure.ac: Set up offload_additional_options,
	offload_additional_lib_paths and offload_targets.
	* testsuite/Makefile.am: Export environment variables: OFFLOAD_TARGETS,
	OFFLOAD_ADDITIONAL_OPTIONS, OFFLOAD_ADDITIONAL_LIB_PATHS.
	* testsuite/Makefile.in: Regenerate.
	* testsuite/lib/libgomp.exp (libgomp_init): Append
	offload_additional_lib_paths to LD_LIBRARY_PATH.  Append
	offload_additional_options to ALWAYS_CFLAGS.  Append liboffloadmic
	build directory to LD_LIBRARY_PATH for intelmic offload targets.
