#
# Yocto upstream doesn't allow compiling kernel for multilib.
# This class helps to reset environment variables required for kernel
# compilation (including modules) for an arch different from default
# tune based on multilib settings. Kernel arch is identified based on
# TARGET_KERNEL_ARCH variable. This class assumes MULTILIB environment
# provides required toolchain packages.
