[Pkg-rust-maintainers] Bug#1102975: librust-opendal-dev is not installable on !amd64/arm64

[Adrian Bunk]

Package: librust-opendal-dev
Version: 0.52.0-1
Severity: serious
X-Debbugs-Cc: Peter Michael Green <plugwash at debian.org>

  librust-opendal-dev:armhf Depends librust-async-backtrace-0.2+default-dev (>= 0.2.6-~~)
  but none of the choices are installable:
  [no choices]


The root cause is #1003070.

Adding librust-async-backtrace-0.2+default-dev would be a way
to limit the architectures where building is attempted.
