updates to linbox-1.7.0, givaro-4.2.0, fflas-ffpack-2.5.0, rebuild sagemath
https://github.com/void-linux/void-packages/pull/42326

Description:
<!-- Uncomment relevant sections and delete options which are not applicable -->
This update is stalled in sagemath (see https://github.com/sagemath/sage/issues/32959) and I don't have a particular reason to do it, but just to be ready. Arch linux uses the updated versions, and the patch needed for sagemath is quite small.

The 3 packages updated (givaro, fflas-ffpack, linbox) need a few small patches just to support i686 and are all taken from and merged upstream.
