Vivado 2017.2 SDK 生成FSBL时存在的bug

SDK 2017.1/.2 - ld.exe: cannot find -lrsa

When importing a new HDF file into the SDK or after a clean of the BSP, the compilation process of some applications can generate a linker error due to not being able to find the RSA library.

具体见xilinx AR# 69517

可以参照AR#69517的方法进行规避，也可以删除工程目录下的SDK文件夹，重新生成FSBL
