There is also the unpleasant option to introduce a rust binary for
architectures other than x86_64, because we can’t bootstrap it
there. It should be noted that this would not be unprecedented.
We have bootstrap binaries for some compilers such as Free Pascal
or GHC.
Adding an old version of librsvg is not obviously the better
option.
