Careful, what does $(@D) refer to here? When it is used here in the file
it is output/build/busybox-*, but when it is expanded in fs/common.mk it
refers to output/images:
cat /home/peko/source/buildroot/output-test/images/busybox.permissions >> /home/peko/source/buildroot/output-test/build/_device_table.txt
cat: /home/peko/source/buildroot/output-test/images/busybox.permissions: No such file or directory

You forgot to append ; \ so it doesn't actually work.
