This function returns True if any of the specified packages are skipped due to
incompatible license.

License exceptions are obeyed. The user may specify the package's license for
cross-recipe checks.

This allows for additions to packagegroups only for non-incompatible builds. For
example:

    RDEPENDS_${PN} += "${@'dbench' if not any_incompatible(d, 'dbench', 
'GPL-3.0-only') else ''}"
