Maybe, but that kind of defeats the point of

 * no compiling dependencies again -- old artifacts are reused

and librsvg's build system seems to use Cargo, so then we again have
the problem that Cargo wants Windows crates etc. that are useless in
Guix and its overly-pickyness in versioning, we lose the ability to let
crates be shared libraries (not yet implemented, but could be
implemented in antioxidant) ..., so I'd rather just implement cdylib
and patch the build system appropriately.

(It's build system is more complicated than ordinary crates, but the
additional Makefile.am isn't too long).
