All examples build for `generic-x86-64`. Replace it with
`generic-armel-iproc` when building for ARM.

## Building additional yocto packages
## Building additional Yocto packages

Assuming the packages you want to add are already present in one of the
layers configured in [`bisdn-linux.yaml`](bisdn-linux.yaml), you can build
them by passing them via `--target` to kas:

```shell
KAS_MACHINE=generic-x86-64 kas build --target lldpd bisdn-linux.yaml -- --runall=do_package_write_ipk

KAS_MACHINE=generic-x86-64 kas-container build --target lldpd bisdn-linux.yaml -- --runall=do_package_write_ipk

We have a separate section on building without containers, the other examples should use kas-container. I realize that I accidentally introduced an example with kas as well, I can fix that or you can add it to this PR, too.

The `--runall=do_package_write_ipk` ensures that not only the package itself,
but also all packages it depends on will be created.

The resulting package and its dependencies will appear in the subdirectories
of `build/tmp/deploy/ipk`. After transferring the package to the switch, it
can be installed with `opkg`:

```shell
opkg install lldpd_1.0.8-r0_corei7-64.ipk
```
