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

[Ming Liu]

Hi, Andre:
The reason for needing this multiconfig to be in OVERRIDES, for me, is the
scenario that I have one recipe but some variables/tasks in it are
different for multiconfig, for instance:

do_install-mc-default () {}

do_install-mc-foo() {}

and I do not want split them into several almost same recipes with only one
task different.
