# ARCH_XTENSA_CORE_NAME is the name of the Xtensa core; empty if none or the
# standard 'fsf' core.
# ARCH_XTENSA_OVERLAY_TAR is the path to the overlay tarball; only valid when
# ARCH_XTENSA_CORE_NAME is not empty.
#
# Example:
# ifneq ($(ARCH_XTENSA_CORE_NAME),)
# tar xf $(ARCH_XTENSA_OVERLAY_TAR) -C $(@D) --strip-components=1 gcc
# endif
