[Pkg-rust-maintainers] Bug#955997: rust-libc: autopkgtest failure.

thanks

The autopkgtest is still failing with rust-libc 0.2.68-1 and rustc 1.42-1

Is it possible to enable/disable (or make non-fatal) autopkgtests on a per-featureset basis? if so should the test for the "dep-of-std" featureset be disabled/made not fatal so we can get this package (and it's reverse dependencies) back into testing?
