	linked to "xgcc", for use when running the JIT library from the
	builddir.
	(MOSTLYCLEANFILES): Add FULL_DRIVER_NAME.
	(install-driver): Use $(FULL_DRIVER_NAME) rather than spelling it
	out.
	* configure.ac (doc_build_sys): New variable, set to "sphinx" if
	sphinx is installed, falling back to "texinfo" otherwise.
	(GCC_DRIVER_NAME): Generate a gcc-driver-name.h file containing
	GCC_DRIVER_NAME for the benefit of jit/internal-api.c.
	* configure: Regenerate.
	* doc/install.texi (--enable-host-shared): Specify that this is
	required when building libgccjit.
