When using Rust on the x86 architecture, we are currently using the unstable target.json feature to specify the compilation target. Rustc is going to change how softfloat is specified in the target.json file on x86, thus update generate_rust_target.rs to specify softfloat using the new option.
Note that if you enable this parameter with a compiler that does not recognize it, then that triggers a warning but it does not break the build.

Applied to `rust-fixes` -- thanks everyone!
[ For future reference, this solves the following error:
RUSTC L rust/core.o error: Error loading target specification: target feature `soft-float` is incompatible with the ABI but gets enabled in target spec. Run `rustc --print target-list` for a list of built-in targets

[ Added 6.13.y too to Cc: stable tag and added reasoning to avoid over-backporting. - Miguel ]
