[CMake] Issue with CMakeDetermineASMCompiler.cmake on 2.8.3

[Emmanuel Blot]

Hello,

I'm not sure if this issue has already been reported, but ithe
following command:
  ENABLE_LANGUAGE (ASM-ATT OPTIONAL)
Triggers the following error, starting at CMake 2.8.3 (worked well up to 2.8.2):

CMake Error at
cmake/Modules/CMakeDetermineASMCompiler.cmake:68
(CMAKE_DETERMINE_COMPILER_ID_VENDOR):
  Unknown CMake command "CMAKE_DETERMINE_COMPILER_ID_VENDOR".
Call Stack (most recent call first):
  cmake/Modules/CMakeDetermineASM-ATTCompiler.cmake:19 (INCLUDE)
  CMakeLists.txt:100 (ENABLE_LANGUAGE)

CMake Error: Error required internal CMake variable not set, cmake may
be not be built correctly.
Missing variable is:
CMAKE_ASM-ATT_COMPILER_ENV_VAR
CMake Error: Could not find cmake module
file:CMakeFiles/CMakeASM-ATTCompiler.cmake
-- Configuring incomplete, errors occurred!
Compilation failed

It seems that adding the following patch fixes the issue:
