[OE-core] [PATCH] meson.bbclass: Add support for nativesdk

[Peter Kjellerstedt]

We need to use the meson.cross file when building for nativesdk.
Additionally, we need to trick meson's sanity tests, just as it is
done for target builds.

I have not tested this extensively, but it at least seems to build
things correctly.
