Summary: Ninja generator should not generate phony commands
with cyclic dependency
Description:
The Ninja generator frequently will generate commands of the form:
--
build testCCompiler.c: phony testCCompiler.c
--
(taken from the build.ninja generated for the initial "-- Check for working C
compiler using: Ninja" step).
This command specifies a cyclic dependency, even though Ninja itself does not
generally error on it:

Steps to Reproduce:
Here is a self contained example:
--
$ cat CMakeLists.txt
cmake_minimum_required(VERSION 3.0)
add_custom_command(OUTPUT foo.tmp DEPENDS foo.c COMMAND true)
add_custom_target(foo DEPENDS foo.tmp)
$ cmake -GNinja .
-- Configuring done
-- Generating done
-- Build files have been written to: /tmp/foo
$ grep "foo.c:" build.ninja
build foo.c: phony foo.c
--
