The GPL is a distribution license. It prevents you distributing Octave
linked with MKL, but doesn't prevent you linking to MKL for your own
purposes as long as you don't share. Hey I don't even need to link
against it. With a little LD_PRELOAD magic on a version of Octave linked
with atlas, I'll get to use MKL instead..
