Maybe the easiest Part would be not to bbappend initscripts and just add
an own reecipe for amlsetfb. Within this recipe I can use
COMPATIBLE_MACHINE.

I guess if I am using  COMPATIBLE_MACHINE in the
initscripts_1.%.bbappend will cause to not build initscripts for any
other machine. :)

Yes I know people do strange things :)
