package-cmake: remove now-redundant target ccache support

Browse source 
All the complexity with the different ways that CMAKE_C_COMPILER and
CMAKE_C_COMPILER_ARG1 can be set are no longer needed, it's all handled
by the toolchain wrapper now.

Note that it is still necessary to handle this for the host build.
