The problem should be the usage of cmake for a native package.

The cmake.bbclass disables the host path and thereby CMake could not 
find the gcc binary.

I think the cmake.bbclass need to distinguish between cross and native 
build and set the following for native build:
set( CMAKE_FIND_ROOT_PATH_MODE_PROGRAM BOTH )
set( CMAKE_FIND_ROOT_PATH_MODE_LIBRARY BOTH )
set( CMAKE_FIND_ROOT_PATH_MODE_INCLUDE BOTH )

This allows CMake to search the binaries, libraries and includes first 
in the CMAKE_FIND_ROOT_PATH, then in the CMAKE_SYSROOT and then in the 
non-rooted directories.
