Source: rust-vhost

Hi,

During a rebuild of all packages in sid, this package failed to build
on armhf.

This package currently has binary packages on armhf, so this is a regression.

Maybe you need to request removal of binaries on armhf/armel/i386?

$ rmadison -S rust-vhost
librust-vhost-dev | 0.10.0-1      | testing    | amd64, arm64, armel, armhf, i386, mips64el, ppc64el, riscv64, s390x
librust-vhost-dev | 0.10.0-1      | unstable   | armel, armhf, i386
librust-vhost-dev | 0.13.0-1      | unstable   | amd64, arm64, mips64el, ppc64el, riscv64, s390x
rust-vhost        | 0.10.0-1      | testing    | source
rust-vhost        | 0.10.0-1      | unstable   | source
rust-vhost        | 0.13.0-1      | unstable   | source

The rebuild was done using an armhf chroot on an AWS "m6g" instance (Graviton2
CPU).
