Subject: csky: port to uclibc-ng

Follow the steps to build c-sky uclibc linux system:
1. git clone https://github.com/c-sky/buildroot.git
2. cd buildroot
3. make qemu_csky_ck810_uclibc_defconfig
4. make

Follow the buildroot/board/qemu/csky/readme.txt to run.

This buildroot toolchain is pre-build, But you can rebuild
the c-sky uclibc-ng alone and install it to the buildroot
sysroot manually.

We'll try our best to improve the uclibc-ng continuously.
