[Buildroot] [PATCH 14/19] package-cmake: remove now-redundant target ccache support

[Romain Naour <romain.naour@openwide.fr>]

Arnout,

Le 20/09/2015 21:28, Arnout Vandecappelle (Essensium/Mind) a ?crit :
> 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.
