I went this approach for now.
That way I get i586 userland and an SDK with both 32bit and 64bit toolchains.
The SDK offers me multiple environment files to include.
What I don't understand right now is, how can i tell the kernel recipe
that it has
to use the 64bit toolchain to build the kernel?
Any hints?
