Setting CMAKE_AR, CMAKE_LINKER and CMAKE_RANLIB correctly in
toolchain.cmake is necessary to correctly build -native packages
using CMake.
The reason is that CMake is not able to find the above utilities by
itself because CMAKE_FIND_ROOT_PATH_MODE_PROGRAM is set to ONLY
so we need to tell it explicitly where to look.
Which version do you use? The master sets
CMAKE_FIND_ROOT_PATH_MODE_PROGRAM to BOTH for native packages.
If this don't work you could set the CMAKE_C_COMPILER_EXTERNAL_TOOLCHAIN
path (without /bin).

You don't need the sed for ranlib.

Why you generate OECMAKE_* and don't use them?
Furthermore the CMAKE_* should contain the full path and are generated
in the CMakeFindBinUtils.cmake.
set( CMAKE_C_FLAGS "${OECMAKE_C_FLAGS}" CACHE STRING "CFLAGS" )
