Fixes #3509

[emilio]

Hmm, the rust for linux job seems to have failed @ojeda:

error: error loading target specification: rustc-abi: invalid rustc abi: 'x86-softfloat'. allowed values: 'x86-sse2', 'powerpc-spe', 'softfloat' at line 3 column 32

Do you know what that is about? I'll try to bump it for now.

That seems to have worked :)

@emilio Upstream Rust changed the target spec files -- I sent commit 905b06d32a52 ("rust: x86: support Rust >= 1.98.0 target spec") in Linux back then to update it:

rust: x86: support Rust >= 1.98.0 target spec

Starting with Rust 1.98.0 (expected 2026-08-20), the target spec will not
support `x86-softfloat` anymore [1]. Instead, `softfloat` should be used,
which is an alias. Otherwise, one gets:

    error: error loading target specification: rustc-abi: invalid rustc abi: 'x86-softfloat'. allowed values: 'x86-sse2', 'softfloat' at line 3 column 32
      |
      = help: run `rustc --print target-list` for a list of built-in targets

Thus conditionally use one or the other depending on the version.

The alias has existed since Rust 1.95.0 (released 2026-04-16) [2], but
use the newer version instead to avoid changing how the build works for
existing compilers, at least until more testing takes place.

So bumping the Linux version was the right thing to do :)

Thanks! (and apologies for the delay -- I was at a conference and missed this)
