Hi, I don't really know how our rust packages are built, but I wonder if 
they have more than the bare minimum optional features for our purposes 
(apart from 1.24 used by icecat and the latest version, we probably 
don't need to build everything)? Maybe it's worth investigating if that 
can speed up the build of the whole chain. It seems we're two versions 
behind current rust too. Is anyone working on packaging them?
