_class-foo works for all types of recipes:
target,native,cross,crosssdk,cross-canadian,nativesdk

classes/base.bbclass:CLASSOVERRIDE ?= "class-target"
classes/cross-canadian.bbclass:CLASSOVERRIDE = "class-cross-canadian"
classes/cross.bbclass:CLASSOVERRIDE = "class-cross"
classes/crosssdk.bbclass:CLASSOVERRIDE = "class-crosssdk"
classes/native.bbclass:CLASSOVERRIDE = "class-native"
classes/nativesdk.bbclass:CLASSOVERRIDE = "class-nativesdk"
conf/bitbake.conf:OVERRIDES = "${TARGET_OS}:${TRANSLATED_TARGET_ARCH}:build-${BUILD_OS}:pn-${PN}:${MACHINEOVERRIDES}:${DISTROOVERRIDES}:${CLASSOVERRIDE}:forcevariable"
conf/bitbake.conf:CLASSOVERRIDE ?= "class-target"

while _virtclass-foo works only for cross, native, nativesdk and multilib
classes/cross.bbclass:    bb.data.setVar("OVERRIDES", e.data.getVar("OVERRIDES", False) + ":virtclass-cross", e.data)
classes/native.bbclass:    e.data.setVar("OVERRIDES", e.data.getVar("OVERRIDES", False) + ":virtclass-native")
classes/nativesdk.bbclass:    e.data.setVar("OVERRIDES", e.data.getVar("OVERRIDES", False) + ":virtclass-nativesdk")
classes/populate_sdk_base.bbclass:        overrides = d.getVar("OVERRIDES", False) + ":virtclass-multilib-" + item
classes/utils.bbclass:        overrides = localdata.getVar("OVERRIDES", False) + ":virtclass-multilib-" + item
recipes-core/eglibc/eglibc-ld.inc:        overrides = localdata.getVar("OVERRIDES", False) + ":virtclass-multilib-" + item

IIRC RP said somewhere that virtclass usages should be 
cleaned from metadata and replaced with stronger CLASSOVERRIDE, that's
why I used class-native here.

Cheers,
