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.

Contrary to all other toolchains, the xcc toolchain had a hardocded
installation path. Replace this with XTENSA_TOOLCHAIN_PATH so users can
install in different locations.

XCC is based on xcc, but is nothing like gcc and his many differences.
Instead of ifdeffing the gcc code with Xcc specifics, maintain it
standalone.

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.
