Thank you for the patch. I applied it to the 2.8.0.

Do I see it right, that this variable is relevant when building CMake itself? I need ABI to be recognized if I compile my own application with CMake, so I can say that this application should be compiled only for EABI. This statement would make ABI check for given GCC (in this case arm-linux-gcc) and reject the compilation if this condition is not satisfied.

The names are appropriate.
