Hello! At some point, building Julia from sources (with `make`) began to imply running the test suite at the end. Is there a secret spell allowing to skip the tests?

Are you sure it was running the test suite, not just compiling the system image? Default `make` does not run the test suite.

I think building OpenBLAS runs tests. Could that be what you saw?  
Using BinaryBuilder OpenBLAS via `USE_BINARYBUILDER_OPENBLAS = 1` in your Make.user would probably be the easiest way to avoid that.

EDIT: Although it will only run these tests when actually building OpenBLAS, which will only happen when you rebuild after Julia upgraded OpenBLAS version.

You’re probably right, my bad. Thanks!
