configure: --enable-racket=auto to simplify cross-compilation

Browse Source 
Using `--enable-racket=auto` causes a Racket for the current platform
to be built in a "local" subdirectory of the build directory as
support for cross-compilation.

This flag is needed because building and installing Racket requires

Use "auto" for RACKET to indicates that one should be built
automatically for the current platform. In that case, `make`
will run `configure` again (with no arguments) in a "local"
subdirectory to create a build for the current platform.
