After I re-build toolchain-llvm-newlib, /data1/zzx/ara/install/riscv-llvm/riscv64-unknown-elf appears, it indicates that the make process is not going as expected(toolchain-llvm-main=>toolchain-llvm-newlib=>toolchain-llvm-rt). So I add the include path manually with export C_INCLUDE_PATH=/data1/zzx/ara/install/riscv-llvm/riscv64-unknown-elf/include, then this problem is solved, but a new problem arises as follows:

I re-build toolchain-llvm-rt, but works nothing.
