I am using RPI3 model B
I have compiled toolchain using crosstool-ng with the following sample.
./ct-ng aarch64-rpi3-linux-gnu
Using ./ct-ng menuconfig, I changed C library from glibc to uClibc. And then toolchain is built with command ./ct-ng build
With this toolchain, I have cross compiled U-Boot for RPI3 model b. I am able to load the boocode.bin, start.elf and U-Boot and able to execute U-Boot commands from the console.
Now I wanted to cross compile the Linux kernel. But I am unable to build with this toolchain. Here are the compilation logs ...

I would like to know if it is possible to compile kernel using this toolchain. If yes, could anybody help me resolve the above errors.
