infra/cross/build-linux.sh builds igneumd and igneum-miner for x86_64-unknown-linux-gnu.2.36 (Debian 12) with
cargo-zigbuild 0.23.4 and zig 0.17.0 into vendor/igneum-node/target-linux: rocksdb, lz4, blst, secp256k1 and the
execution layer all link through zig, no crate failed (Docker is absent here, so cross was not needed). Cold build
1,856 s at 4 jobs, nice 19, on a loaded Mac; the seed's own build took 55 min and the builder VM 10 to 25.
Verified on igneum-seed-1 in /root/xbuild-test: igneumd --version, igneum-miner --help, and a 60-s private
network with real proof of work where the cross-compiled miner found 7 blocks that the cross-compiled node
accepted (0 rejected). /opt/igneum/v4/bin untouched.
BIN_SOURCE=mac: provision.sh skips the builder VM and takes build/bin from the cross-compile; stage-v4.sh
cross-compiles, uploads to /root/v4/out and installs exactly as a VM build would.
