Just like the previous commit did for the pkg-generic infrastructure, this commit improves the pkg-kconfig infrastructure to declare its custom <pkg>-<something> targets as PHONY.

# Kconfig package infrastructure
|
|
#
|
|
# This file implements an infrastructure that eases development of
|
|
# package .mk files for packages that use kconfig for configuration files.
|
|
# It is based on the generic-package infrastructure, and inherits all of its
|
|
# features.
|
|
#
|
|
# See the Buildroot documentation for details on the usage of this
|
|
# infrastructure.

# inner-kconfig-package -- generates the make targets needed to support a

# kconfig package

|
#
|
|
# argument 1 is the lowercase package name
|
|
# argument 2 is the uppercase package name, including a HOST_ prefix

|

# argument 3 is the uppercase package name, without the HOST_ prefix
