[Luo Zhenhua-B19537] I think above code is compatible with the defconfig usage in SRC_URI, defconfig defined in SRC_URI has the high priority. User can easily by add custom defconfig by append it in SRC_URI. 
	BTW, menuconfig should be the better way to do kernel configure, isn't it?

[Luo Zhenhua-B19537] FSL maintains the kernel defconfig in kernel source for all QorIQ targets, so we want Yocto to get defconfig from kernel source directly to ensure the recent defconfig will be built.
