简化过程的交叉编译内核的图像

Currently, this script only supports cross compilation for ARM architecture, but I intend on adding support for other architecture based on demand. The purpose of the script is to automate many of the processes required for building a uImage that will boot using the uBoot loader, especially on the Buffalo Linkstation Pro platform. Use this script if you find building kernels an infrequent but enduring process of: Remembering what you did before. How to do it again.
