Note that CMake has very good support for using clang as a cross compiler 
and will add the required flags.

Note also that any time I've tried using the ubuntu packaged clang as a 
cross-compiler it has not worked. I talked to the package maintainer about 
that at one point, and using clang as a cross compiler was out of scope for 
his packages, so you have to not use those packages.
