	(enable_as_accelerator): New variables substituted by configure.
	(libsubdir, libexecsubdir, unlibsubdir): Tweak for the possibility of
	being configured as an offload compiler.
	(DRIVER_DEFINES): Pass new defines DEFAULT_REAL_TARGET_MACHINE and

	install for the offload compiler.
	* config.in: Regenerate.
	* configure: Regenerate.
	* configure.ac (real_target_noncanonical, accel_dir_suffix)
	(enable_as_accelerator): Compute new variables.
	(ACCEL_COMPILER): Define if the compiler is built as the accel compiler.
	(OFFLOAD_TARGETS): List of target names suitable for offloading.
	(ENABLE_OFFLOADING): Define if list of offload targets is not empty.

gcc/doc/
	* install.texi (Options specification): Document
	--enable-as-accelerator-for and --enable-offload-targets.
gcc/fortran/

	* configure: Regenerate.
	* configure.ac (accel_dir_suffix): Compute new variable.
	(extra_parts): Add crtoffloadbegin.o and crtoffloadend.o

	(enable_offload_targets): Support Intel MIC targets.
	(OFFLOAD_TARGETS): List of target names suitable for offloading.
lto-plugin/
