When ZEPHYR_TOOLCHAIN_VARIANT is of the form toolchain/compiler, it needs to be split into the toolchain (which overwrites ZEPHYR_TOOLCHAIN_VARIANT) and compiler (stored in
TOOLCHAIN_VARIANT_COMPILER).
Otherwise, when defined, it is left alone. When undefined it is set to "zephyr".
Finally, if the value is "zephyr" and no TOOLCHAIN_VARIANT_COMPILER setting is present, then TOOLCHAIN_VARIANT_COMPILER is set to "gnu".
This allows existing configurations which set ZEPHYR_TOOLCHAIN_VARIANT to "zephyr" to work with the new SDK and allows Zephyr to easily support both old and new variable settings during the SDK transition period.
