buildrootschalter/package/pkg-generic.mk
Thomas De Schampheleire 4d5bf929a6 infra: permissions/users/device tables: avoid adding empty entries 
In pkg-generic.mk, an entry would be added to each of the permissions,
devices and users tables, even if FOO_PERMISSIONS/DEVICES/USERS is empty. In
that last case, the entry would contain only the separator, which is
substituted to '\n' in fs/common.mk.
For configurations with many packages, this would render the build output a
bit odd, containing many \n instances (even though the end result in the
target would of course be the same).

This patch cleans up the build output by only adding to these tables when
the package actually specified contents for them.

# Generic package infrastructure
#
# This file implements an infrastructure that eases development of
# package .mk files. It should be used for packages that do not rely
# on a well-known build system for which Buildroot has a dedicated
# infrastructure (so far, Buildroot has special support for
# autotools-based and CMake-based packages).
#
# See the Buildroot documentation for details on the usage of this
# infrastructure
#
# In terms of implementation, this generic infrastructure requires the
# .mk file to specify:
#
# 1. Metadata informations about the package: name, version,
# download URL, etc.
#
# 2. Description of the commands to be executed to configure, build
# and install the package
