you can now specify rustflags on a per-target basis in .cargo/config: ``` toml [target.x86_64-unknown-linux-gnu] rustflags = ["x86", "specific", "flags"] [target.arm-unknown-linux-gnueabi] rustflags = ["arm", "specific", "flags"] ``` If both build.rustflags and target.*.rustflags are specified, the target.* ones will be used. As before RUSTFLAGS overrides either set. closes rust-lang#3153

@alexcrichton Done, I think. Is just config.md enough? |

@bors: r+ Thanks! |
