qoriq_build_64bit_kernel: Document the multilib promotion block

The block conditionally replaces KERNEL_CC, KERNEL_LD and KERNEL_AR. A
declarative form would have to state what those keep when the flag is
unset, which means restating the kernel.bbclass defaults inside this
class. DEPENDS is also read before the task graph exists, so a task
cannot carry any of this.
