The defconfig check has been introduced by the previous
patch before the building each defconfig but those builds
are done every week or more.
Checking if a defconfig is valid can be done on every
push in the repository since it take few seconds.
This would allow to detect as soon as possible a problem
in a defconfig and eventually avoid breaking the build
while build testing all defconfig.
Introduce a new job template ".defconfig_check" in
gitlab-ci.yml.in and modify the generate-gitlab-ci-yml
to create a job for each defconfig to run the test.
Although, we could have used only one job to do all
tests, using one job per defconfig allow to identify
easily in gitlab which defconfig is falling.

make-4.3 shipped with a backward incompatible change in how sharp signs
are handled in macros. Previously, up to make 4.2, the sharp sign would
always start a comment, unless backslash-escaped, even in a macro or a
fucntion call.
Now, the sharp sign is no longer starting a comment when it appears
inside such a macro or function call. This behaviour was supposed to be
in force since 3.81, but was not; 4.3 fixed the code to match the doc.
As such, use of external toolchains is broken, as we use the sharp sign
in the copy_toolchain_sysroot macro, in shell variable expansion to
strip off any leading /: ${target\#/}.
Fix that by applying the workaround suggested in the release annoucement
[0], by using a variable to hold a sharp sign.

Some packages test for CMAKE_SYSTEM explicitly[1]
CMAKE_SYSTEM is comprised of CMAKE_SYSTEM_NAME and CMAKE_SYSTEM_VERSION.
It defaults to CMAKE_SYSTEM_NAME if CMAKE_SYSTEM_VERSION is not set[2]
At the point CMAKE_SYSTEM_NAME is set to "Linux" CMAKE_SYSTEM is already
constructed. Setting it explicitly ensures that it is the correct value.
This is because we do set CMAKE_SYSTEM_NAME twice, in fact:
- first in toolchainfile.cmake, so that we tell cmake to use the
"Buildroot" platform,
- second, in the Buildroot.cmake platform definition itself, so that
we eventually behave like the Linux platform.
We also set CMAKE_SYSTEM_VERSION to 1, and so the real CMAKE_SYSTEM
value should be set to Linux-1 if we were to follow the documentation to
the letter.
However, for Linux, the version does not matter, and in some situations
may even be harmful (that was reported in one of the commits that
introduce Buildroot.cmake and toolchainfile.cmake).

In 36568732e4, we expanded toolchain.cmake to also define the value for
CMAKE_SYSTEM_VERSION, as the cmake documentation states that it must be
manually defined when doing cross-compilation [0]:
When the CMAKE_SYSTEM_NAME variable is set explicitly to enable
cross compiling then the value of CMAKE_SYSTEM_VERSION must also
be set explicitly to specify the target system version.
However, the fix in 36568732e4 uses the version of the kernel headers,
assuming that would be the oldest kernel we could run on. Yet, this is
not the case, because glibc (for example) has fallbacks to support
running on kernels older than the headers it was built against.
The cmake official wiki [1] additionally states:
* CMAKE_SYSTEM_VERSION : optional, version of your target system, not
used very much.
Folllowed a little bit below, by:
* CMAKE_TOOLCHAIN_FILE : absolute or relative path to a cmake script
which sets up all the toolchain related variables mentioned above
For instance for crosscompiling from Linux to Embedded Linux on PowerPC
this file could look like this:
# this one is important
SET(CMAKE_SYSTEM_NAME Linux)
#this one not so much
SET(CMAKE_SYSTEM_VERSION 1)
[...]
Furthermore, using the kernel headers version can be a bit misleading (as
it really looks like is is the correct version to use when it is not),
while it is obvious that 1 is not really the output of `uname -r` and
thus is definitely not misleading.
Finally, random searches [2] about CMAKE_SYSTEM_VERSION, mostly only
turns up issues related with Windows, Mac-OS, and to a lesser extent,
Android (where it is forcibly set to 1), with issues realted to running
under just Linux (as opposed to Adnroid) mostly non-existent.
Consequently, we revert to using the value that is suggested in the
cmake WiKi, i.e. 1, and which is basically what we also used as a
workaround in the azure-iot-sdk-c paclkage up until d300b1d3b1.
A case were we will need to have a real kernel version, is if we one day
have a cmake-based pacakge that builds and installs a kernel module [3],
because it will need the _running_ kernel version to install it in
/lib/modules/VERSION/, but in that case it will anyway most probably
not be the headers version.

Quoting the CMake documentation:
When the CMAKE_SYSTEM_NAME variable is set explicitly to enable cross
compiling then the value of CMAKE_SYSTEM_VERSION must also be set
explicitly to specify the target system version.
Thus, we should also set CMAKE_SYSTEM_VERSION in toolchainfile.cmake. It
is supposed to be set to the value of `uname -r` on the target. We don't
have that exact value available (unless we build the kernel), but the
value of BR2_TOOLCHAIN_HEADERS_AT_LEAST contains the (minimum) version
of the kernel it will run on, so it should be OK for all practical
purposes.

Currently, we tell cmake where to look for our own custom platform
description by passing the path to the moduls directory on the command
line.
However, this causes two different problems.
First, some packages simply set CMAKE_MODULE_PATH in their
CMakeList.txt, thus overriding our own path, and then our platform
description is not found.
Second, cmake may internally call sub-cmake (e.g. in the try_compile
macro), but the CMAKE_MODULE_PATH is not automatically passed down in
this case.
For the first problem, we could hunt down and fix all offenders, but
this is an endless endeavour, especially since packagers are told to do
so on the cmake wiki [0]:
CMAKE_MODULE_PATH
tell CMake to search first in directories listed in
CMAKE_MODULE_PATH when you use FIND_PACKAGE() or INCLUDE()
SET(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/MyCMakeScripts)
FIND_PACKAGE(HelloWorld)
The second problem could be solved by passing yet another variable on
the command line, that tells cmake to explicitly pass arbitrary
variables down to sub-cmake calls:
-DCMAKE_TRY_COMPILE_PLATFORM_VARIABLES=CMAKE_MODULE_PATH
However, this only covers the case of try_compile. Even though no other
case is known yet, we'd still risk missing locations where we would need
to propagate CMAKE_MODULE_PATH, even some where we'd have no solution
like for try_compile.
Instead, ngladitz on IRC suggested that CMAKE_MODULE_PATH be set
directly from the toolchain file.
And indeed this fixes both problems explained above.
So be it.

The handling of RPATH in cmake-3.7 has changed drastically, causing a
slew of build failures dues to libraries from the host being pulled in:

- libcec : http://autobuild.buildroot.org/results/3f3/3f3593bab7734dd274faf5b5690895e9424cbb89/
- and so on...
The bug was reported upstream [0], which dismissed it altogether [1] as
being expected behaviour, quoting:
I don't think there is anything wrong with that change on its own.
It merely exposed some existing behavior in a new case.
Instead, upstream suggested in that same message that a platform
definition be used instead, quoting:
If a toolchain file specifies CMAKE_SYSTEM_NAME such that a custom
`Platform/MySystem.cmake` file is loaded then the latter can set
them as needed for the target platform.
So here we are doing so:
- we add a new platfom definitions that inherits from the Linux one,
then overrides the problematic settings;
- we change our toolchain file to use that platform instead;
- we tell cmake where to find additional modules, so that it can find
our custom platform file.
This has been tested to work in the following conditions:
- pre-installed host cmake, versions 3.5.1 (Ubuntu 16.04) and 3.7.2
(manually built)
- internal cmake, versions 3.6.3 (the current version as of this
patch) and 3.7.2 (with the followup patches).
Thanks to Jörg, Ben and Baruch for the help investigating the issue.
Special thanks to Jörg for handling the discussion with upstream and
pointing to the relevant messages! :-)

From the build configuration, Buildroot defines and set some compiler
and linker flags that should be passed to any packages build-system.
For package using the cmake-package infrastructure, this is achieved
via the toolchainfile.cmake.
This change simplifies the way the toolchainfile.cmake file handles
these flags: it now just sets them, without any attempt to extend them
with those Buildroot defined.
This change still allows overriding these flags from the configure
command line.
So, now, when a CMake-based package needs to extend them, they should
be fully set from the package *.mk file. This behavior is consistent
with what is done for others package infrastructures.
This change should not pull any regression WRT the bug #7280 [1].
However, now, when someone uses the toolchainfile.cmake file outside of
Buildroot, he/she must overload all compiler/linker flags (including the
ones Buildroot sets since they no longer get automatically added).

When a build type is set, CMake does append some flags that can override
those set by Buildroot due to the gcc option parser (in which the last
argument controling an option wins).
Hereafter is a summary of the optimization and debug flags set by
Buildroot and appended by CMake.
* Flags set by Buildroot depending on the configuration:
BR2_ENABLE_DEBUG | Optim. level | Buildroot {C,CXX}FLAGS
=================+=====================+=======================
y | BR2_OPTIMIZE_S | -Os -gx
y | BR2_OPTIMIZE_G | -Og -gx
y | BR2_OPTIMIZE_{0..3} | -On -gx
n | BR2_OPTIMIZE_S | -Os
n | BR2_OPTIMIZE_G | -Og
n | BR2_OPTIMIZE_{0..3} | -On
* Default flags appended by CMake depending on the build type:
Build type | Flags | Effects on {C,CXX}FLAGS
===============+=================+===========================================
Debug | -g | Force -g, compatible with BR2_ENABLE_DEBUG
MinSizeRel | -Os -DNDEBUG | Set -Os, compatible with BR2_OPTIMIZE_S
Release | -O3 -DNDEBUG | Set -O3, closest to the others cases,
| | though the optimization level is forced.
RelWithDebInfo | -O2 -g -DNDEBUG | Force -g and set -O2, not friendly with BR
To avoid the CMake flags take precedence over the Buildroot ones, this
change sets in toolchainfile.cmake the per-config compiler flags CMake
can append depending on the build type Buildroot defined.
So, CMake does not mess up with the compilation flags Buildroot sets.
It is still possible to override these per-config flags on the cmake
command line.
Note:
If a CMake-based project forces the compiler and/or linker flag
definitions (the default ones or the per-config ones - e.g.
CMAKE_C_FLAGS/CMAKE_C_FLAGS_{DEBUG,RELEASE}), there is not much
Buildroot can do about it.
So, the flags will be overwritten anyway in these cases.

Currently, it is not possible for a br2-external tree to override a
defconfig bundled in Buildroot, nor is it possible to override one from
a previous br2-external tree in the stack.
However, it is interesting that a latter br2-external tree be able to
override a defconfig:
- the ones bundled in Buildroot are minimalist, and almost always
build a toolchain, so a br2-external tree may want to provide a
"better" defconfig (better, in the sense "suited for the project");
- similarly for a defconfig from a previous br2-external tree.
But we can't do that, as the rules for the defconfigs are generated in
the order the br2-external trees are specified, all after the bundled
defconfigs. Those rule are patten-matching rules, which means that the
first one to match is used, and the following ones are ignored.
Add a new utility macro, 'reverse', inspired from GMSL, that does what
it says: reverse a list of words.
Use that macro to reverse the list of br2-external trees, so that the
latters win over the formers, and even over bundled ones.

pkg-utils.mk contains various definitions that are used in the package
infrastructures and packages themselves.
However, those definitions can be useful in other parts of Buildroot,
and are already used in a few places that are not related to the package
infrastructure. Also, $(sep) will be needed early in the Makefile when
we eventually support multiple br2-external trees.
Since this file only contains definitions, we can include it anytime.
So, consider that file to no longer be specific to the package infras:
- move it to support and rename it,
- move a few similar definitions from the main Makefile to that file.
