[CMake] TI-C CMAKE_C_LINK_EXECUTABLE order

[Florian Reinhard]

Hi Falk,

the TI Docs contains the following line:
cl6x --run_linker {--rom_model | --ram_model} filenames
[options] [--output_file= name.out] --library= library [lnk.cmd]

therefore i'd suggest the following changes:
set(CMAKE_C_LINK_EXECUTABLE   "<CMAKE_C_COMPILER>   --run_linker <OBJECTS>
<CMAKE_C_LINK_FLAGS>   <LINK_FLAGS> --map_file=<TARGET>.map
--output_file=<TARGET> <LINK_LIBRARIES>")
set(CMAKE_ASM_LINK_EXECUTABLE "<CMAKE_ASM_COMPILER> --run_linker <OBJECTS>
<CMAKE_ASM_LINK_FLAGS> <LINK_FLAGS> --map_file=<TARGET>.map
--output_file=<TARGET> <LINK_LIBRARIES>")
set(CMAKE_CXX_LINK_EXECUTABLE "<CMAKE_CXX_COMPILER> --run_linker <OBJECTS>
<CMAKE_CXX_LINK_FLAGS> <LINK_FLAGS> --map_file=<TARGET>.map
--output_file=<TARGET> <LINK_LIBRARIES>")

I'm using it on a c++ project, linker language is c, the c/c++ line above
works for me. I didn't test ASM, but i guess that's straight forward.

Maybe Alex Neundorf  can do this change .

Regards,
 Florian
