Comment:
I updated this branch to the new "sage-as-a-python-module" version from #35339 which seems to work very well.

The previous approach with its full history is at https://github.com/tornaria/void-packages/tree/sagemath-v1, rebased to current master. I won't be updating or rebasing it further.

Assuming CI passes (should take about 2h to finish), this PR is done and ready to merge. Any problems we find later we can follow up in individual issues, please @ me so I'm notified.

We have:
 - 11 patches which can be upstreamed, I'll work on that.
 - 2 patches are taken from positive_review tickets in sage trac, should be merged soon.
 - only 2 are void specific, no patches that are musl specific.
