The toolchains were built according to the instructions of the official RISC-V GNU Compiler Toolchain repository using Ubuntu 20.04 LTS on a 64-bit x86 machine (actually on Ubuntu on Windows). The compressed toolchain archives are available as releases assets.
These prebuilt toolchains are used by the NEORV32 RISC-V Processor project.
Toolchain prefix: riscv32-unknown-elf or riscv64-unknown-elf

Click on the according download link in the table above to directly download the archive of choice from the according release page via the release assets.
You can use wget to directly download a toolchain archive from the table above. Select the toolchain of
choice, right-click on the download link, click "copy link address" and use that as argument for wget. Example:
$ wget https://github.com/stnolting/riscv-gcc-prebuilt/releases/download/rv32i-1.0.0/riscv32-unknown-elf.gcc-10.1.0.rv32i.ilp32.newlib.tar.gz
git clone of the repository will not include the release assets so it will not include the actual toolchain archives!
Create a folder where you want to install the toolchain, for example /opt/riscv (you will need
sudo rights to create this folder and copy data to it).
$ sudo mkdir /opt/riscv
Navigate to the download folder. Decompress your toolchain (replace TOOLCHAIN with your toolchain archive
of choice). Again, you might have to use sudo if your target directory is protected.
$ sudo tar -xzf TOOLCHAIN.tar.gz -C /opt/riscv/
Now add the toolchain's bin folder to your system's PATH environment variable (or add this line to your .bashrc if applicable):
$ export PATH=$PATH:/opt/riscv/bin
Test the toolchain:
$ riscv32-unknown-elf-gcc -v
