[OE-core] [PATCH V2] bitbake.conf: add BB_CURRENT_MC to OVERRIDES

[Ming Liu]

Yes, that is true, but then I will need have a mc-default override set in
local.conf any way, since I need distinguish the build for all
multiconfigs, that makes me think it'd better to have a single
mc-${BB_CURRENT_MC} set in OVERRIDES.
