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.
