Split up the toolchain configuration into two phases, generic and
target. The 'generic' phase configures the toolchain just enough to be
able to preprocess DT files. The 'target' phase completes the
configuration with target-specific configuration.

Align 'clang' with 'gcc' by having it also use 'find_program' instead
of 'set' to assign toolchain paths.

Align 'clang' with gcc by having it also set CMAKE_C_COMPILER in the
'compiler' build script instead of the 'toolchain' build script.

The 'llvm' and 'clang' build scripts have been named strangely. It is
more natural for 'clang' to be the compiler, and 'llvm' to be the
toolchain.
This commit rectifies this by renaming the files.
This also fixes#11187

Fixed whitespace such that 'XTOOLS_TOOLCHAIN_PATH' is vertically
aligned.
Also, combined two cmake invocations of 'list' into one.

ARCH is available before CONFIG_ARCH, and is otherwise identical. So
it is better to use ARCH than CONFIG_ARCH as this allows the code to
be moved around more freely.

Drop the seemingly unused XCC_BUILD variable because it depends on
Kconfig and we need to cut the toolchain's dependency on Kconfig.
Signed-off-by: Sebastian Bøe <sebastian.boe@nordicsemi.no>
When we move DT infront of Kconfig we are going to need access to a C
toolchain before Kconfig is evaluated. This means it will not be
possible to specify the toolchain used through Kconfig.
To deal with this we ...
Drop support for specifying CROSS_COMPILE through Kconfig. Still
available is the ability to specify CROSS_COMPILE through the
environment or through a CMake variable.

XCC does not support the "-undef" flag so set NOSYSDEF_CFLAGS to
empty string to fix compile warning.
Also, XCC does not supply the macro __SIZEOF_LONG__ which breaks
the build. So define it.

The old GCC ARM Embedded website on launchpad
(https://launchpad.net/gcc-arm-embedded) has been superseeded by the new
GNU Arm Embedded one
(https://developer.arm.com/open-source/gnu-toolchain/gnu-rm).
This also means a change of name from "GCC" to "GNU". Reflect this in
the enviroment variables so that the proper term is used henceforth.

Latest crosstools NG supports ARC, so add it here for those who build
their own toolchains using xtools-ng or use the scripts from sdk-ng repo
in the zephyr project.

Add an LLVM backend and a clang toolchain variant to support building
with llvm coming with popular Linux distributions.
This has been tested with X86 boards:
- quark_d2000_crb
- quark_se_c1000_devboard/Arduino 101
Use:
export ZEPHYR_TOOLCHAIN_VARIANT=clang

The Kconfig option TOOLCHAIN_VARIANT (not to be confused with
ZEPHYR_TOOLCHAIN_VARIANT) is a legacy configuration option that has
very few use-cases and can easily be dropped.
It's functionality is easily covered by CONFIG_X86_IAMCU and
ZEPHYR_TOOLCHAIN_VARIANT.
This commit removes all references of it from Zephyr.

This patchset provides Xtensa's xcc compiler support for Xtensa
projects in Cmake. This requires the below environment variables
to be defined aptly. The appropriate xcc license information also
need to be supplied.

If the value argument to set_ifndef() may be unset, the entire value
must be double-quoted to avoid a CMake syntax error.
Fix call sites which don't handle this, or which otherwise make
non-idiomatic use of this function.

Move toolchain definitions into toolchain/ and move compilers to
compilers/
Usage of toolchain- for everything was confusing, there are the actual
compiler related definitions and there is the toolchain/SDK related
configs, so keeping them separate helps understand the different and
prevents confusion.
