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.
