multilib: Add support for cross-canadian multilib packages

Add support for the generation of cross-canadian packages.

Each cross-canadian package has:
 PN = "pkg-cross-canadian-${TRANSLATED_TARGET_ARCH}"

in order for that to be evaluated properly with multilibs enabled, it was
necessary to detect both the presence of the cross-canadian packages and
then update the vars using the OVERRIDE for the multilib.  Additional checks
were made to ensure that any dependency that sais "cross-canadian" did not
get prefixed with the MLPREFIX.

Also, make sure that even when building multilib cross-canadian packages,
we only use the single SDK PACKAGE_ARCH, we don't want or need variants.
