Once upon a time anybody using a Unix-like OS was familiar with most of those standard targets as a consequence of the ubiquity of autotools, especially when package repositories weren't so comprehensive and it was more common to download and build tarballs locally.

But at my current job, there's no rhyme or reason to make targets. Something like `make build` (where build may or may not be the default target, likely accidentally if it is) is more likely to install Go toolchain dependencies than to build any of the project source code. And of course little if any attempt is made to actually declare dependencies, correct or broken, as for so many programmers these days a Makefile is just a container for ad hoc shell code.

I don't often make use of autotools in my own projects as I can usually get good mileage from plain POSIX make, switching to GNU make in a bind, but I religiously try to adhere to the standard targets and other build and distribution conventions outlined at https://www.gnu.org/software/make/manual/html_node/Makefile-... and https://www.gnu.org/prep/standards/standards.html#Managing-R...
