chore: fix RISC-V guest build on macOS 26 Add .cargo/config.toml setting CFLAGS_riscv32im_risc0_zkvm_elf to "-march=rv32im -nostdlib". This prevents cc-rs from injecting macOS-specific flags (-arch arm64, -mmacosx-version-min) into the riscv32-unknown-elf-gcc cross-compiler when building C dependencies (e.g. ring) for the guest target, which causes build failures on macOS 26 Tahoe. 2026-04-29 09:45:53 +02:00			`[env]`
