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).

The chosen CMAKE_BUILD_TYPE encodes an option of the Buildroot
configuration, so it makes more sense to save it in the
toolchainfile.cmake than to pass it during configure.

It is still possible to override the build type on the cmake
command line.

Since the rsync of skeleton or rootfs now changes the permissions of
the copied files and directories, this may break existing setups that
rely on these permissions being kept. So add a release note explaining
how it should be done.
