Right. Closing as not a (PHP) bug.

So, it seems that the root cause of this issue is that the libaom versions currently provided by
Debian APT and Alpine APK systems are not functional (AFAIK they are compiled without the required
BUILD_SHARED_LIBS=1, but I may be wrong here).
So, in order to make imageavif() and imagecreatefromavif() work, you need to do everything by hand:
1. compile and install libaom
2. compile and install libdav1d (to decode AV1)
3. compile and install libyuv (used by libavif to better handle YUV decoding)
4. compile and install libavif
5. compile and install the gd PHP extension (with the --with-avif flag)
For an example about how that can be done in Debian (so, Ubuntu too) and Alpine, you can take a look
at https://github.com/mlocati/docker-php-extension-installer

I filed MR to upgrade libavif in Alpinelinex 3.14 but looks it needs major version bump for libaom,
meantime it should be working in alpine:edge

I think this is the same thing that Pierre kindly fixed here:

This issue is still live with version 8.1.0beta3
Same test procedure, but used docker image php:8.1.0beta3-fpm-buster

Hmm, I wonder whether we need to explicitly configure a codec for
libavif on some platforms. Apparently, pkg-config doesn't do this
here.
