Good to see them go.  :-)

Could you please also remove the files and remove them from
‘gnu/local.mk’?

This is unnecessary; if you could avoid it, that’d be great: it’d make
the important changes more visible.

Looks like this hunk is mostly reformatting as well?

I understand the intent and that’s fine, but I would prefer a solution
that does not explicitly refer to MKL.  Perhaps we could devise a
solution that, more generally, allows users to swap one BLAS for
another, but maybe that’s beyond the scope of this patch.

Could you send a v2 of the patch that addresses these comments?

Bonus points if you can provide a commit log that follows the ChangeLog
style:

Thank you,
