Without the crosscompiling and building for x86-64 I was able to reach far into the compilation of scipy.

I have issues with how libgfortran deploys it’s file so that scipy can see them. I found an OpenBlas recipe that I use to configure/build scipy with the site.cfg file.

I skipped atlas for now.
