242e0087e5 core: move pkg-utils.mk to support/
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.

e8c3755676 pkg-cmake.mk: set CMAKE_SYSROOT variable in toolchainfile.cmake
This change enforces the CMAKE_SYSROOT value set in the toolchainfile.cmake.

This fix overrides the CMake heuristics used to guess it, and turns off some
non-desirable behavior adding "-isystem ..." flags to the compiler command
line, misleading the compiler and making the build failed due to some
unfound standard headers.

e31ad0e809 package-cmake: remove now-redundant target ccache support
All the complexity with the different ways that CMAKE_C_COMPILER and
CMAKE_C_COMPILER_ARG1 can be set are no longer needed, it's all handled
by the toolchain wrapper now.

Note that it is still necessary to handle this for the host build.

c1e41153e6 pkg-cmake.mk: Set CMAKE_SYSTEM_PROCESSOR.
This is rarely needed by packages, but convenient to have when it is.

[Thomas:
  - don't define ARM_VARIANT as this name is too global, use
    CMAKE_SYSTEM_PROCESSOR_ARM_VARIANT instead.
  - don't use ifndef, but a more traditional else clause, for the
    non-ARM cases.]

47544e43a5 toolchainfile.cmake.in: do not force the CMAKE_{C, CXX}_FLAGS to the cache
Fix #7280 [1]

When the FORCE option is passed to the set command, the variable is
added/updated in the CMake cache every single time CMake processes this
command.

Because the toolchainfile.cmake prepends architecture/toolchain flags
to the CMAKE_{C,CXX}_FLAGS, this makes the CFLAGS being updated in the
generated Makefiles each time one reconfigures its project. So it
forces the compilation of everything, even when nothing has changed.

c8f2d248f6 pkg-cmake.mk: enable ccache for cmake packages
This patch updates the generated toolchainfile.cmake to use ccache.

When toolchainfile.cmake is used inside Buildroot, using ccache during
the build is driven by a CMake knob: USE_CCACHE, automatically set by
the cmake-package infrastructure and reflecting the BR2_CCACHE value.

Since this toolchainefile.cmake file can be used outside Buildroot, and
this file also set a couple of things (among these: the sysroot cflag,
some pkg-config environment variables), it is important to set the
compiler variables as well to keep the consistency of the
cross-compilation configuration.
So, when it is used outside Buildroot, using ccache for the build is
driven by the ccache program availability.

Note that using ccache for the build is achieved by setting the *_ARG1
CMake variables to let CMake use ccache without failing in detecting
the compiler.

85fea5d953 pkg-cmake.mk: refactor the toolchainfile.cmake generation
This patch introduces a toolchainfile.cmake.in template which is filled
by Buildroot.

Using a toolchainfile.cmake.in template file allows to avoid overloading
quoting and/or escaping and it becomes much more similar to the
resulting file.

This patch also cleans up the quoting style.

9226a9907c Warn the user about the usage of output/target as the root filesystem
A very common mistake done by our users is that they use
output/target/ directory as their root filesystem. Even though this is
loudly documented in our Buildroot manual, people don't read
documentation, so it is not sufficient.

This patch adds a text file named
output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM which explains why
output/target isn't appropriate to use as the root filesystem. The
process is:

 * At the beginning of the build, right after the skeleton has been
   copied, support/misc/target-dir-warning.txt is copied to
   output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM

 * In the filesystem images creation code, this file is removed before
   launching fakeroot, and restored right after that, so that this
   file is not present in the generated root filesystem images.

Note that the file has not been added to the default skeleton for two
reasons:

 * It would have annoying to have in our source tree a file named in
   capital letters inside system/skeleton/

 * The proposed way works even if the user uses a custom skeleton.
