d/rust-1.38.0-x86_64-1.txz
It seems that rust-1.38.0 builds fewer shared objects causing the package
size to bloat to almost double. I held this back overnight to compile some
modified builds to see if the old build behavior could be restored but
didn't have any luck, so I'll put this out as-is for now. Any help debloating
this package would be appreciated. Note that it also had to be bootstrapped
from the official binaries using LOCAL_BOOTSTRAP=NO. That's not all that
unusual for Rust, but perhaps that's another problem…
