2) Building for foreign architectures using qemu system emulator.

osc is offering now to use any hardware architecture. (Thanks a lot
for the initial implementation of that code!). For example

osc build --vm-type=qemu openSUSE_Factory_ARM aarch64

will build for aarch64 on your x86_64 workstation for example.
But it should work for any architecture.
The downside (compared to our former qemu user land emulation)
is that it works way slower due to emulation overhead and it
works currently only in projects where a kernel-obs-build is defined.

The "standard" repository of openSUSE:Factory:RISCV is setup for user land qemu
This is conflicting, so you need to use "native" repository.

However, I noticed there are also some pieces still missing for RISCV in osc &
And we need to have riscv enabled in our qemu package. Will check with Andreas
later today hopefully about this.
