This is just a heads up that GCC has switched so that the toplevel
coordinates the bootstrapping.
The main change is that on a native configuration `make' will
automatically bootstrap, unless you configure with --disable-bootstrap
(and, since the binutils list is receiving this message, if you
bootstrap a combined tree, the assembler and linker will also be built
three times, each time using the previous one). There should be no
behavior change for cross configurations, nor for trees not including GCC.
