There's something I don't understand. Most BLASes try at compile time to
figure out what the optimal build flags are and how to produce the
best binary (e.g. which vector instructions the CPU supports, etc).
How can this work for distributing a compiled BLAS? Does the OpenBLAS
build know how to delegate these questions to runtime instead of
compile time?

You mean vs ATLAS? We haven't shipped a reference BLAS with Octave for
a long time.
