 Note that the binaries in the Ka-Ro supplied rootfs will most likely not work,
unless you also reuse their toolchain.

 Reusing their toolchain is BTW pretty easy as well: copy the toolchain out of
the VM and install it in the same location on your host, and in buildroot select
'External toolchain', 'custom toolchain', 'pre-installed toolchain', and point
'toolchain path' to where the toolchain resided (excluding the bin/ part). Then
you'll have to specify the toolchain properties: which standard C library is
used (most likely glibc), the gcc version, and the kernel headers version. If
you make a mistake there, buildroot will tell you what is wrong.

 One possible issue you may run into is that they also have custom versions for
some of the user-space programs, e.g. for bluetooth or wifi support. If that is
the case, it is probably easiest (to start with) to use the vendor-supplied
toolchain as I described above and just copy those binaries from the
vendor-supplied rootfs.

 Arnout
