> Can you elaborate on why you would use uname -m instead of instructing the person building the software to configure the build correctly for their system? (it's not hard in my experience)

It's also not hard in my experience, but mysteriously, it seems to be hard for my users. This creates endless support load for you. Yes, "those users should not use my software" is a valid choice, but if you want to support those users, automatic build setup is pretty much necessary.

I too wish my users would just follow the instruction which is easy. Unfortunately, wishing does not solve the problem.
