+git clone https://github.com/riscv-collab/riscv-gnu-toolchain.git
+cd ./riscv-gnu-toolchain
+
+git submodule update --init --recursive
+
+mkdir ./build && cd ./build
+
+# Setup to build newlib.
+./configure --prefix=/usr/local/
+make -j4 newlib
+
+# Some Example options below.
+make -j4 build-gcc1
+make -j4 build-gcc2
+make -j4 build-gdb
