Subject: [PATCH] ci: skip host rustup for mipsel-softfloat (docker handles its
 toolchain)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

v1.1.0 CI run (24820831905) failed at the dtolnay/rust-toolchain@stable
step for the mipsel-unknown-linux-musl matrix entry: that target is
tier-3 in stable Rust and `rust-std` isn't available via rustup, so
the `targets:` parameter errors out with

    error: component 'rust-std' for target 'mipsel-unknown-linux-musl'
    is unavailable for download

before the docker step that actually builds it ever runs. The docker
image we use (`messense/rust-musl-cross:mipsel-musl-softfloat`) bundles
its own Rust + std, so the host-level rustup isn't needed here at all.

Gated by `matrix.mipsel_softfloat != true` so the other 8 targets still
install their toolchain the normal way. `continue-on-error: true` on
the job level already prevented this from blocking the release, but
the failure was noisy and confusing — fix makes the whole matrix green.

Pushed as a small follow-up to v1.1.0 so the re-tag picks it up.
