Print the name of the discovered toolchain as well as the variable
used to initialize it.
This is nice to know when doing remote support, since users will
sometimes misconfigure their toolchain and not know what that means.

Xtensa requires building a new toolchain for a specific SoC.
By default xtools built Xtensa toolchains all have prefix of
xtensa-zephyr-elf. In order to distinguish different toolchains,
they are now placed in their own directories under their SoC
name. This allows us to have multiple Xtensa toolchains
targeting multiple SoCs.
The additional level in path name is introduced in SDK v0.11
and sdk-ng master.

This forms the foundation for the abstraction of the binary tools,
where the following steps are taken:
- Move binary tool resolving, such as objcopy, objdump, readelf and
so forth, out of compiler definitions and place in a dedicated binary
tools folder with the binary tools supplier as subfolder, similar to
the compiler and linker directories.
- Create binary tool sets, gnu, host-gnu and llvm.
- Each toolchain selects the required set of binary tools by setting
BINTOOLS via its generic.cmake as it also does for compiler and linker.
The intent here is to abstract Zephyr's dependence on toolchains,
thus allowing for easier porting to other, perhaps commercial,
toolchains and/or usecases.
No functional change expected.

Found a few annoying typos and figured I better run script and
fix anything it can find, here are the results...

The LINKER variable is introduced to follow the same logic and flow as
the existing COMPILER variable: That is, each TOOLCHAIN is responsible
for choosing COMPILER and LINKER.
Currently, Zephyr's build system is hardcoded for GNU ld.
Reflect this in LINKER by letting all existing toolchains use GNU ld.
No functional change expected.
This is motivated by the wish to abstract Zephyr's usage of toolchains,
permitting non-intrusive porting to other (commercial) toolchains.

Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier. Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.
By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

When using xtools as toolchain, cmake searches the toolchain home
directory. However, if the first toolchain directory does not
begin with any character before "s", "sources" (if exists) would
become the first directory being probed. Since it does not
conform to "arch-vendor-abi" naming, cmake would fail.
So exclude "sources" from the list to avoid this issue.

newlib is not supported with this toolchain, so mark it as such and
filter tests based on the variable defined in the toolchain file.

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.
