therealaleph 6541eb013f ci: mipsel-softfloat — use mipsel-musl image + RUSTFLAGS=+soft-float ...

The image tag I assumed existed (`mipsel-musl-softfloat`) isn't
published by messense; docker-pull errored with "manifest unknown".
Available mipsel tags are just `mipsel-musl` (hardfloat) and the
regional mirrors of same.

Fix: use `messense/rust-musl-cross:mipsel-musl` (the standard
hardfloat image) and force soft-float code generation via
`RUSTFLAGS=-C target-feature=+soft-float` on top of the nightly
`-Z build-std=std,panic_abort` we were already using. build-std
recompiles libstd with the same RUSTFLAGS, so libstd itself comes
out soft-float even though the image's gcc/musl is hardfloat. We
don't link anything beyond libc for mhrv-rs (ring is pure-asm for
the crypto hot paths), so the fact that musl libm isn't soft-float
doesn't bite us.

Net result: the binary emits no hardware FP instructions, which is
what MT7621 actually needs.
