Summary:                    Infinite loop when reconfiguring with different
CMAKE_C_COMPILER
Description: 
It's possible to get CMake stuck in a seemingly infinite loop when reconfiguring
a project.

Steps to Reproduce: 
1. Create the following trivial CMakeList.txt:
~~~~
cmake_minimum_required(VERSION 2.8.8)
~~~~

2. `cd` to the directory containing this file, and execute `cmake .`
3. Execute `cmake . -DCMAKE_C_COMPILER=cc`

Expected Behaviour:
CMake reconfigures the project with the specified compiler.

Actual Behaviour:
CMake prints the following to stdout in an infinite loop:
~~~~
-- Configuring done
You have changed variables that require your cache to be deleted.
Configure will be re-run and you may have to reset some variables.
The following variables have changed:
CMAKE_C_COMPILER= cc
~~~~
