Summary:                    Older versions of TI compilers do not support
--output_file
Description: 
I have a project which is tied to some old compiler of TMS470 4.1.4. This
version still does not support --output_file nor -fe switch. Regular way to go
was to use -fr switch.

In order to support also older versions of TI compilers (which also is valid for
new ones), replace in TI-C.cmake:

set(CMAKE_C_COMPILE_OBJECT  "<CMAKE_C_COMPILER> --compile_only --c_file=<SOURCE>
<DEFINES> <FLAGS> --output_file=<OBJECT>")

With:

set(CMAKE_C_COMPILE_OBJECT  "<CMAKE_C_COMPILER> --compile_only --c_file=<SOURCE>
<DEFINES> <FLAGS> --obj_directory=<OBJECT_DIR>")
set(CMAKE_C_OUTPUT_EXTENSION_REPLACE   1)

Even better, --obj_directory should be replaced with -fr option (see
http://public.kitware.com/Bug/view.php?id=14879).

Keep in mind though, that <OBJECT_DIR> changed semantics recently, so it is
needed to update the issue together with
http://public.kitware.com/Bug/view.php?id=14876.
