I don't know. Among the packages based on this is libreoffice, which I'm
guessing many people who would use it would never install it if they
always needed to build it from source. Based on the notes in maths.scm on
openblas, `#:substitutable? #f' also disables offloading, so while we don't
want to serve the file from hydra, we don't want to prevent people from
offloading the build to a more powerful machine. Is there a way that we
can mark that it hasn't been built yet on hydra? Or can we change the
error message for when it fails to download a file from hydra to:

Package "foo" failed to download. This may be because:
1. not yet built on hydra
2. fails to build, please help fix
3. broken pipe, try again

If you would like to try building it on your machine to work around 1 or
3, please add '--fallback' to your command.
