Hello Guix!

It seems our LAPACK substitute is now different than what is offered
upstream:

Investigating a bit with diff, one can find that many hidden files have
been cleaned up from the release:

The attached patch fixes the hash, and an issue was opened here [0] to
let the maintainers know of the problem.

I've built lapack myself with this change and all the tests still pass.

Thanks,

Maxim
