cargo xbuild does not completely take into account the --target-dir option and still uses the ./target folder for certain things.

This target folder can cause the Nix build to fail (not finding the correct core crate).

``cargo xbuild`` does not completely take into account the ``--target-dir`` option and still uses the ``./target`` folder for certain things. ```text src> ls artiq-zynq-env armv7-none-eabihf.json Cargo.lock Cargo.toml libdyld Makefile runtime szl zc706.py src> cargo xbuild --release -p runtime --target-dir ../build/firmware artiq-zynq-env Updating crates.io index [...] Finished release [optimized + debuginfo] target(s) in 0.06s src> ls artiq-zynq-env armv7-none-eabihf.json Cargo.lock Cargo.toml libdyld Makefile runtime szl target zc706.py src> find target/ artiq-zynq-env target/ target/sysroot target/sysroot/lib target/sysroot/lib/rustlib target/sysroot/lib/rustlib/x86_64-unknown-linux-gnu target/sysroot/lib/rustlib/x86_64-unknown-linux-gnu/.sentinel target/sysroot/lib/rustlib/x86_64-unknown-linux-gnu/bin target/sysroot/lib/rustlib/x86_64-unknown-linux-gnu/bin/llvm-size target/sysroot/lib/rustlib/x86_64-unknown-linux-gnu/bin/llvm-profdata target/sysroot/lib/rustlib/x86_64-unknown-linux-gnu/bin/llvm-objcopy target/sysroot/lib/rustlib/x86_64-unknown-linux-gnu/bin/llvm-nm [...] ``` This ``target`` folder can cause the Nix build to fail (not finding the correct core crate).

Setting an additional env XBUILD_SYSROOT_PATH=$(pwd)/../build/sysroot works around that. Seems to need an absolute path here.

Okay, I'll update the Makefile
