    autobuild: Add test for cross-compilation infrastructure
    
    With added option to generate cross-answers by cross-execute script,
    a test is added to verify that at least for tested build environments,
    the infrastructure is self-consistent.
    
    The test runs samba configuration in three modes:
    1. Native
    2. Cross compile with cross-execute, using the build machine as its own
       target
    3. Cross compile with cross-answers, using the answers generated in
       step 2
    
    The build environments created by the three processes are then tested to
    be equal.
