Comment 10 for bug 2004516

Slight change here - this isn't needed for libaom3.

Due to the good use of non-embedded libs we now have correct dependency tracking.
That shows that only aom-tools would needed it, which isn't pulled in from libheif.

We could promote it, but if you want that you'd need to seed aom-tools (if it is serving a good purpose) in one of the -supported seeds I guess.
