Define the CMAKE_CROSSCOMPILING_EMULATOR variable similar to what the meson bbclass does. This allows for example to execute cross compilied unit tests on the build machine. CMAKE_CROSSCOMPILING_EMULATOR is a semi colon separated list of paramters which could directly handle the -L and the -E parameters. Creating a wrapper script is not absolutely mandatory. But anyway lets do it similar to what the meson.bbclass does and also disable pseudo.
