I presume this is just temporary to demonstrate that the PR passes?
There was a problem hiding this comment.
Yes, exactly. That's also why I made it a separate commit, so that it's easy to revert / rebase away.

This is a companion PR for python-pillow/Pillow#5201 (and python-pillow/pillow-depends#37). It adds scripts to build libavif wheels for manylinux1 and os x.
A few notes:
AOM required two changes to build on manylinux1—one to deal with the old version of perl, and another to
#definean intrinsic that has a different name in the glibc on el5.While I was working on these scripts I ran into some flakiness with crates.io. The recommended way to avoid such issues with rust CI builds is to "vendor" the crate dependencies. To that end, I included a rav1e vendor tar.gz file in python-pillow/pillow-depends#37. Also included in that PR is a script to generate new rav1e vendor archives. Despite the complexity building rav1e adds, I still think its inclusion is worthwhile because of how much faster it is compared to aom.
I'm not currently building rav1e on 32-bit because there are only 64-bit binaries for cargo-c releases. If this strikes folks as problematic, I could either look into opening a pull request against cargo-c to add 32-bit builds to their CI, or build cargo-c from source here (though I'd likely have to add a crate vendor tar.gz file for cargo-c to pillow-depends).
SVT-AV1 was too much of a hassle to build for manylinux1, though I am still building it for the os x wheels here. I'm open to removing this codec altogether.
In summary: all wheels include the aom codec for encoding and decoding, and the dav1d codec for decoding. 64-bit wheels include rav1e, and OS X has the SVT-AV1 codec.
