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.

This change prevents CMake from searching outside the sysroot location
for CMake modules when cross-compiling.

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.]

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.

The linker flags are part of the toolchain configuration, so set them for
the CMake-based 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.

The patch allows sharing or moving the toolchains.
This is a step toward making the toolchain/sdk relocatable.

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.
