Yes, I know - It's the same kind of issues we have with busybox/uclibc
configuration file if you change version.

Alternatively we can split it up and provide an option for the base
device table (which will default to target/generic/device_table.txt) and
add an option for static device nodes (which defaults to
target/generic/device_table_dev.txt) and only make that option visible
if static dev is used.

The makefile can then concatenate those options and use them like it is
done today.
