CVS commit: pkgsrc/lang/rust

["Taylor R Campbell" <riastradh%netbsd.org@localhost>]

Module Name:    pkgsrc
Committed By:   riastradh
Date:           Tue Nov 10 13:42:40 UTC 2026

Modified Files:
        pkgsrc/lang/rust: cargo.mk

Log Message:
lang/rust/cargo.mk: Set CARGO_BUILD_JOBS=${_MAKE_JOBS_N} in MAKE_ENV.

This fixes excessive parallelism in py-maturin, anything that uses
Python setuptools-rust, and generally anything that assembles its own
cargo(1) command line instead of using ${CARGO_ARGS}.
