die is meant to be a more flexible exit, printing a message to go with
the exit call. It works like:
die -- same as "exit 1"
die "It just broke." -- echo statement, exit value 1
die "Tried to do the thing." "2" -- echo statement, exit value 2
Exit codes other than 1 require a message to go with it.
it would replace existing code that looks like:
echo "ERROR: Everything went wrong. Sorry!"
exit 1
or be more helpful in picking up the pieces when something unexpected
happens then:
do_something || exit 1

This reorganizes functions based on their purpose as well as strives to declare
a function prior to another function calling it. No changes in how any function
is implemented.
Purpose groupings:
Function - functions that make it easier to implement other functions
Buildsystem - functions around the build environment
Package - functions that work with packages or configure them
Kernel - functions for getting information on the kernel/firmware
Addon - functions around building kodi addons
Target Configuration - Functions that set something up on the target

eglibc ceased active development years ago and is no longer in tree, so no need
to check for it.
tolower() has been around since 2010 and is unused anywhere. Wish it well!
Should it return, tr '[:upper:]' '[:lower:]' is likely better.

Storing the cache in an exported environment variable can
result in build failures if the cache exceeds the MAX_ARG_STRLEN
limit (128k on linux) which can be triggered by building in a
rather deeply nested directory.

Split up the LTO flags in config/optimize and assemble
full C/CXX/LDFLAGS in config/functions.
Add flags for parallel/single-threaded lto and fat/non-fat
lto object creation.
Change the default lto build flag to use non-fat lto objects.

Packages are only built with LTO if it's explicitly enabled via
the lto build flag or if a package enables LTO via configure / cmake
options.
Enabling LTO via configure / cmake is the preferred way as this
gives packages more fine grained control, eg enable parallel LTO
linking etc. When doing this packages should respect the
LTO_SUPPORT setting so LTO can be disabled globally.
To avoid conflicting C/CXX/LDFLAGS no FLAGS are added when the
lto build flag is not set.

- replace strip_lto/strip_gold (only allowed to disable)
- add flag for PIC feature
- add flag to stop build parallel
- add support for hardening option (initial copy from debian 9)
All build parameters, are added in setup_toolchain.
`PKG_[FLAG]_[HOST/TARGET]_ENABLED` variable is introduced for checking the flag (yes/no) in the package.mk
Thanks to @MilhouseVH, for support and fixing
this is needed for devices that require specific packages for
example u-boot, we can keep changes within the device folder
rather than adding multiple definitions to the project package
