Toolchain: Make `/path/comp;-argn' behave the same as 'comp;-argn'
When using `cmake ... -DCMAKE_C_COMPILER=gcc;-pipe` first invocation of CMake worked correctly. When using `cmake ... -DCMAKE_C_COMPILER=/path/to/gcc;-pipe` first invocation of CMake detected a change to CMAKE_C_COMPILER, printed "You have changed variables" message, and re-ran the initial compiler tests after configuration was complete and before generation of the project files. The difference was due to the cache being forced updated with the new value of CMAKE_C_COMPILER so that the comparison check passes.
