Rustup's toolchain can be compiled normally with xargo in 2020-04, but it will not work after rustup is updated. Do I need to add any parameter configurations?

Transferred to rust-lang/rust, as this does not appear to be a cargo issue.

Also, you may want to specify more information about your project (is this hello-world, or something more complicated?).

I've been seeing the same thing trying to compile for mipsel-unknown-linux-uclibc. I found these issues that also may be related:
