In cvs HEAD there are two ways how the compiler file may be named:
either <SYSTEM>-<basename-of-the-compiler-executable>.cmake
(which would give Generic-chc12.cmake)
and additionally
<SYSTEM>-<compiler-id>.cmake
where <compiler-id> is determined by compiling a small test program and
encoding a compiler identification string in it, which could be
e.g. "FreeScaleCHC12". This way the name would/will be unique.
(leaves the problem that it can't link by default).

Then many more of the tests in cmake just work and less manual tweaking is
required.
