Thanks @rgommers , this is a very nice writeup. I've been wanting to get a quick crash-course on the latest with the NumPy build system and this fits the bill perfectly.
I left a couple minor comments which can be safely ignored, otherwise this LGTM!

Thanks, this is very useful! A few small in-line comments.

Was it intended to have a link for Netlib?

It wasn't, but added now for clarity. I meant it as "Netlib BLAS (i.e., Reference BLAS)"

This is a complete build docs overhaul, bringing everything up to date after the switch to Meson. A lot of content is taken from http://scipy.github.io/devdocs/building/index.html and adapted for NumPy (spin, Fortran compiler requirement, etc.). The main added content is for BLAS/LAPACK.
I on purpose did not touch the contributing guide, that will be done in a follow-up. These from-scratch docs should cover everything, and build-related info that is duplicate in the contributing guide will disappear in a next PR.
EDIT: after this is merged, the backlink from https://numpy.org/install/ needs updating too.
