Browse Source 
- setup.sh: ./setup.sh <kernel-repo-path>, unpacks to <kernel-parent>/toolchain/
- README.md: install + build instructions
- clang-11.0.1 (AOSP 6443078) + binutils-2.27

# setup.sh - 解压工具链到母项目 (android_kernel_eebbk_sm6150) 旁边
# setup.sh - 解压构建工具链到内核仓库
#
# 用法:
# git clone <toolchain-repo> # 克隆工具链仓库
# cd <toolchain-repo> # 进入
# ./setup.sh # 运行, 会把工具链放到母项目同级目录
# ./setup.sh <内核仓库路径>
#
# 最终目录结构:
# 例:
# git clone <toolchain-repo>
# cd <toolchain-repo>
# ./setup.sh ~/android_kernel_eebbk_sm6150
#
# 效果: 工具链解压到 <内核仓库路径>/../toolchain/ (与内核仓库同级)
# <parent>/
# ├── android_kernel_eebbk_sm6150/ <- 内核源码
# ├── android_kernel_eebbk_sm6150/ <- 内核仓库
# └── toolchain/
