rustup gave a warning when trying to install the i686-* toolchain:

error: DEPRECATED: future versions of rustup will require --force-non-host to install a non-host toolchain.
warning: toolchain '1.71.1-i686-unknown-linux-gnu' may not be able to run on this system.
warning: If you meant to build software to target that platform, perhaps try `rustup target add i686-unknown-linux-gnu` instead?

What's happening is that the host is actually an x86_64 (using the OS image ubuntu-22.04 from GitHub), although it is possible to run 32-bit programs using lib32 libraries. The ideal solution is

  • installing an x86_64-unknown-linux-gnu toolchain, and
  • adding an i686-unknonwn-linux-gnu target, and
  • invoking cargo build and other cargo commands with the --target command line option.
    • Alternatively we can override the default build target in Cargo.toml.

Use host toolchain and explicit target
eecf96b 
This fixes a problem of installing i686 toolchain on an x86_64 host.
Instead, we use the x86_64 toolchain, but add the i686 target and force
all cargo commands to use that target using the `CARGO_BUILD_TARGET`
environment variable.

Fixes: mmtk#1107

Use host toolchain and explicit target in CI script (#1109)
86da9e9 
This fixes a problem of installing i686 toolchain on an x86_64 host when
running "Minimal tests - mmtk-core" on GitHub CI. Instead, we use the
x86_64 toolchain, but add the i686 target and force all cargo commands
to use that target using the `CARGO_BUILD_TARGET` environment variable.
