There are three main parts to a build system: figuring out what the possible commands are, figuring out which of those commands need to run and in which order, and actually running them.
While a shell script would conceivably be able to express the first one, it would struggle with some of the the second part (especially around incremental builds), and a readable implementation of the third part would likely be sequential, resulting in impractically long build times.
