looks strange, but works:
BBCLASSEXTEND = "native"
IS_NATIVE = "no"
IS_NATIVE_virtclass-native = "yes"
INHERIT += " ${@base_conditional("IS_NATIVE", "no", "autotools cmake",
"autotools", d)}"

looks even better, and still works:
INHERIT_CLASSES = "autotools cmake"
INHERIT_CLASSES_virtclass-native = "autotools"
INHERIT += ${INHERIT_CLASSES}

looks even better, and fails somehow :/:
INHERIT_CLASSES = "cmake"
INHERIT_CLASSES_virtclass-native = ""
inherit autotools ${INHERIT_CLASSES}

looks better, but fails:
INHERIT_CLASSES = "autotools cmake"
INHERIT_CLASSES_virtclass-native = "autotools"
inherit ${INHERIT_CLASSES}
-> ParseError: Could not inherit file classes/autotools cmake.bbclass

Tested only by checking -e output!
