Problem: When package configuration fragments defined in a separate file included from base package Makefile
OpenWRT can't track changes in Package/<name>/config variable correctly.
Cause: In OpenWrt when you move part of package confgiuration to separate files you should use the following
trick in Makefile:
SCAN_DEPS=part_of_package.mk
-include part_of_package.mk
In this case changes in "part_of_pacakge.mk" would trigger regenration of "tmp/info/.packageinfo-<path_to_package>"
file. The "tmp/info/.packageinfo-<path_to_package>" file used in generation of "tmp/.packageinfo" and
"tmp/.config-package.in" files that used for OpenWRT defconfig infrastructure.
Unfortunately OpenWrt implementation can't correctly track cases when such "part_of_package.mk" deleted.
Solution: Add md5sum from string with dependency names as dependecy for "tmp/info/.packageinfo-<path_to_package>"
file. The code reuse OpenWRT trick that already used for "tmp/.packageinfo" dependencies
