Toolchain building utilities

• Another solution is to use utilities that automate the process of building the toolchain

• Same advantage as the pre-compiled toolchains: you don't need to mess up with all the details of the build process

• But also offers more flexibility in terms of toolchain configuration, component version selection, etc.

• They also usually contain several patches that fix known issues with the different components on some architectures

• Identical principle: shell scripts or Makefile that automatically fetch, extract, configure, compile and install the different components
