    labs/sysdev-thirdparty: add sufficient info in cross-file.txt
    
    Just specifying the cross-compiler is not sufficient for meson: the
    build fails with:
    
    /lib/ld-uClibc.so.0: No such file or directory
    meson.build:1:0: ERROR: Executables created by c compiler arm-linux-gcc are not runnable.
    
    because it tries to run target executables on the build machine.
    
    Fix this by passing the appropriate [host_machine] section in
    cross-file.txt.
