[PATCH 03/18] move generated_files order-only dependency later


There is an order-only dependency in gcc/Makefile.in that tries to
build the generated files before compiling regular objects.  However,
this appears too early, and so at the time it is seen by make,
GCOV_OBJS and GCOV_DUMP_OBJS have not yet been set.

This patch fixes the problem and prevents any future problems of this
nature by moving the order-only dependency to the end of Makefile.in.

This also adds lto-wrapper.o to ALL_HOST_BACKEND_OBJS.

	* Makefile.in (ALL_HOST_BACKEND_OBJS): Add lto-wrapper.o.
	($(ALL_HOST_OBJS)): Move order-only dependency to end
	of file.
