Kernel in a Linux system shouldn't be multilib, thus setting NO_MULTILIB
flag for kernel.bbclass. Besides if other recipes have dependency on
virtual/kernel or kernel-module-*, we don't extend name for them.

Some part of the commit is derived from Ke's prototype in:
http://bugzilla.pokylinux.org/show_bug.cgi?id=1361
