[Pkg-rust-maintainers] Bug#947709: (no subject)

[Wolfgang Silbermayr]

A quick investigation reveals:

* We have the "@" test (currently called command1 in the quoted log)
  which enables all crate features. The clang-sys crate does not permit
  enabling both the "runtime" and the "static" features at the same
  time, so the build script intentionally aborts with a compiler error.
  We will mark this test as FLAKY with the test_is_broken debcargo
  config flag for the next rust-clang-sys release.
* The other tests fail because they attempt to run the `llvm-config`
  tool which isn't installed. I tested with the llvm and clang moved
  from the Recommends to the Depends field. This could be fixed by using
  the Depends field in the autopkgtests control. I don't know if
  debcargo is already able to output that field, maybe we have to
  implement it there first.
