    multiconfig: Enable multiconfig dependencies on oe-core
    
    This patch enables multiconfig dependencies (mcdepends) to be used on
    recipes using the following format:
    
    task[mcdepends] = "multiconfig:FROM-MC:TO-MC:PN:task-to-depend-on"
    
    For the sake of simplicity consider the following example:
    
    Assuming we have set up multiconfig builds, one for qemux86 and one for
    qemuarm, named x86 and arm respectively.
    
    Adding the following line to an image recipe (core-image-sato):
    do_image[mcdepends] = "multiconfig:x86:arm:core-image-minimal:do_rootfs"
    
    Would state that core-image-sato:do_image from x86 will depend on
    core-image-minimal:do_rootfs from arm so it can be executed.
    
    This patch makes modifications to bitbake.conf to enable mcdepends, and
    to sstatesig and staging.bbclass to avoid conflicts between packages from
    different multiconfigs.
