Comment:
Same here, on 64 bit (glibc and musl) only the single failure due to giac-1.7

On i686:

This is due to a faulty sympow on i686, see https://github.com/void-linux/void-packages/pull/34209#issuecomment-976444205

These 3 in polyhedron might also be caused by miscompilation of some external program or library, it would be useful to try to see which external packages are used in those files, remove them from makedepends and recompile/rerun these tests.

In addition to those I also had (on i686)
```
sage -t --random-seed=335940497943411300414171505300249115189 src/sage/functions/orthogonal_polys.py  # Timed out
```

No idea if this is related, but it could also be due to some miscompilation.


> Btw, do we need `linbox` in makedepends at the moment? see `linbox-1.6.3.p1: standard, will be installed as an SPKG`

No, linbox is not picked up from system yet, there is https://trac.sagemath.org/ticket/29631 which I'll try later. Note that the message is different for packages not found (something like "pkg is not available from system, will be installed as SPKG").
