Subject: Support cross-building the stage1 and stage2 components

This requires a feature recently added to BuildStream (in commit
03906221) that adds a framework for elements to support being
cross-compiled.

To build an armv8l64 native toolchain and sysroot on an x86_64 build
machine, for example, you can do this:

    bst build --target-arch=armv8l64 gnu-toolchain/stage2.bst

You can then run `bst checkout` to get at the resulting binaries and
copy them onto an armv8l64 machine where they can be executed.
