    bitbake: cooker.py: new multiconfig '*' syntax support
    
    Currently you cannot build a target for all the configured multiconfigs without
    specifying a list. The list can be quite long, requiring to type several lines
    of text.
    
    This enhancement is to support globbing so that you can do this,
    e.g. instead of:
    
        $ bitbake multiconfig:A:bash multiconfig:B:bash bash
    
    you can do:
    
        $ bitbake multiconfig:*:bash
    
    There are real world use cases where it is desirable to use multiconfig with
    two different tasks. For example:  SDKs with multiple toolchains but also
    containing set of additional host tools, or multiconfig builds requiring one image for
    the  main CPU(s) and a different co-image for a companion CPU.
    For this reason, two variations of the new syntax are supported.
    
    For example, the following:
    
        $ bitbake multiconfig:*:meta-toolhchain
    
    would expand to:
    
        $ bitbake multiconfig:A:meta-toolchain multiconfig:B:meta-toolchain meta-toolchain
    
    However the following:
    
        $ bitbake multiconfig:*:meta-toolhchain hosttools
    
    would expand to:
    
        $ bitbake multiconfig:A:meta-toolchain multiconfig:B:meta-toolchain hosttools
    
    In other words, if the user specified the "default" task explicitly, it replaces the implicit
    "default" task.
