I'm not really happy with having 2 ways of specifying per-package
permissions, but OK - perhaps it is the best way of handling this.

Alternatively we could drop the check-for-empty <pkg>_PERMISSIONS in
pkg-generic.mk, so PACKAGES_PERMISSIONS only get expanded at filesystem
creation time and then do something like:

BUSYBOX_PERMISSIONS = \
        $(if $(shell grep 'CONFIG_PING=y' $(BUSYBOX_BUILD_CONFIG)),/bin/ping f 4755 0  0 - - - - -$(sep)) \
        $(if $(shell grep 'CONFIG_PING6=y' $(BUSYBOX_BUILD_CONFIG)),/bin/ping6 f 4755 0  0 - - - - -$(sep))
        ...

But that also isn't very pretty.
