Re: [Pkg-rust-maintainers] Bug#881845: Bug#881845: Bug#881845: Bug#881845: Bug#881845: Bug#881845: Bug#881845: Bug#881845: rustc: FTBFS on mips*: test failures

add Dragan Mladjenovic, who is maintaining rust for mips.

@Dragan can you help to debug rustc on mips64el, we have some test failures.

I noticed that we allow more test failures on some arch.
Can we also do it for mips64el for temporary?
