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.
