As I was surprised by the new rust dependency, I looked at
https://github.com/GNOME/librsvg/blob/master/COMPILING.md. Indeed, Rust
appears to be necessary.

But the other thing that came up from this reading is:

Mandatory dependencies
[...]
GObject-Introspection 0.10.8

But we don't have gobject-introspection in Buildroot, the package for
that is pending review, and it's a complicated one. How is it possible
that you built librsvg without it ? Is the documentation incorrect and
in fact it's an optional dependency ?
