Saikrishna Arcot 8970425a75 Fix calculation of $(1)_DEP_PKGS_SHA in Makefile.cache (#10764)
In Makefile.cache, for $(1)_DEP_PKGS_SHA, the intention is to include
the DEP_MOD_SHA and MOD_HASH of each of the current package's
dependencies. However, there's a level of dereferencing missing; instead
of grabbing the value of $(dfile)_DEP_MOD_SHA, it is literally using the
variable name $(dfile)_DEP_MOD_SHA. This means that the value of this
variable will not change when some dependency changes.

The impact of this is in transitive dependencies. For a specific
example, if there is some change in sairedis, then sairedis will be
rebuilt (because there's a change within that component), and swss will
be rebuilt (because it's a direct dependency), but
docker-swss-layer-buster will not get rebuilt, because only the direct
dependencies are effectively being checked, and those aren't changing.

# DPKG caching framework
#
# SONiC source code composes of multiple open source modules. Eg: Linux, bash, ntp etc.
# Each module considered as a build target in the sonic build framework.
# Each module gets compiled and generate the final debian package(.deb) file.
# There are two types of source code packages used by the SONiC repo.
#
# 1. Module source code is maintained as part of main repo
# Eg: sonic-utilities, Plaform files etc
#
# Some module source code is maintained outside the sonic repo, but
# the build framework is part of sonic main repo.
# The build framework downloads the zipped source content from the web,
# applies a series of patches (if applicable) on the downloaded source code,
# compiles the source and generates the final .deb package(s).
# Eg: bash, ntp, etc
#
# 2. Module source code is maintained as a submodule(SM) in the sonic repo.
# Eg: Frr, swss, Linux etc
#
#
# The sonic build framework uses the module .deb packages that are generated as part of build and
# creates the set of target docker images and the final binary image for distribution.
#
# The caching framework provides the method to cache the module .deb packages and docker images
# into a cache location by tracking module dependency information.
#
# A module can have a set of dependency files, for example Makefiles, source files, scripts, dpkg control files, etc.
# The caching is done based on the SHA hash value of the module dependency file contents. If one of the
# dependency files is changed, the corresponding cache file is also changed. So it automatically creates the new cache file
# for that module.
#
# It provides two levels of caching.
# Global cache := Module doesnt have any local changes.
# Local cache := Used for target when one of its dependency file is modified.
#
#
# Steps for adding new module is given as a template.
# Template File : rules/template.dep
#
# Common files and FLAGS
# Run the 'touch cache.skip.common' command in the base directory to exclude the common files from caching

# DPGK framework creates three dependency files for each target.
# 1. Flags file (.flags)
# 2. Dependency file (.dep),
# 3. Dependecy SHA hash file (.sha)
# 4. If the target is a submodule, corresponding dependency file and hash file are created
# sub module dependency file (.smdep)
# sub module hash file (.smsha)
# For example: following are the cache framework files for bash module
# target/debs/stretch/bash_4.3-14_amd64.deb => Final debian package
# target/debs/stretch/bash_4.3-14_amd64.deb.flags => Environment Flag file
# target/debs/stretch/bash_4.3-14_amd64.deb.dep => Dependency files list
# target/debs/stretch/bash_4.3-14_amd64.deb.dep.sha => SHA Hash file
#
#
# [1] .flags => contains value of all the environment variables of a target.
# Each target can have dependency with one or more environment variable.
# For example:
# SONIC_DEBUGGING_ON=y
# SONIC_PROFILING_ON=y
# SONIC_SANITIZER_ON=y
# etc
# If any of the ENV flag variables are modified, the target needs to be rebuilt as
# the content of flag file is changed becase of value of ENV variable is changed.
#
# [2] .dep => contains the dependency files list for a target. Eeach traget can have one or more dependency files.
# If any of the ENV flag variables are modified, the target needs to be rebuilt.
# For example: Dependency files list for 'bash' module
# rules/bash.mk
# rules/bash.dep
# src/bash/Makefile
# etc
#
# [3] .sha => contains the 48 byte SHA value for each dependency file present in the .dep file.
# For example:
# 9604676527653dcf7b6046fdda7ba52026b7f56f rules/bash.mk
# 191c345c1270776b3902c9ec91d5e777e0b5e2a3 rules/bash.dep
# 55692fe59303554b5958b04aa62c3651bc34bb6a src/bash/Makefile
# etc
#
# If module target is a sub module in the sonic repo, the following additional files gets created for that target.
# .smdep => contains the dependency files list
# .smsha => contains the SHA hash value for .smdep files list.
# ruiles for <.flags> file creation
#
# Each target defines a variable called '_DEP_FLAGS' that contais a list of environment flags for that target and
# that indicates that target needs to be rebuilt if any of the dependent flags are changed.
# An environmental dependency flags file is created with the name as <target name>.flags for each target.
# This file contains the values of target environment flags and gets updated only when there is a change in the flag's value.
# This file is added as a dependency to the target, so that any change in the file will trigger the target recompilation.
# For Eg:
# target/debs/stretch/linux-headers-4.9.0-9-2-common_4.9.168-1+deb9u3_all.deb.flags
#
# RULE args:
# $(1) => target name
# $(2) => target destination folder path
# $(3) => target file extension
# $(4) => additional flags
#
# It updates the _DEP_FLAGS variable if there is any change in the module flags.
