[CMake] [Dev] CMake 2.5 tool chain support example

I still think I should use vendor ("Freescale") instead of "Generic", as
"Generic-chc12" may not be unique, it is just luck that two different
vendors have differently named compilers, so using this as the
discrimination just seems wrong (I've actually got three different
compilers for the HC12).

Thanks, I'll try this when I'm back from my road trip.

The compiler flags aren't the issue, the link/locator needs a custom
control file (see "link.prm" in the previous attachment), and defaulting
this isn't possible without also including a copy, it is possible, but
why bother? What benefit does the compiler test give?
