2019-03-15Auto merge of #58575 - mati865:musl_toolchain, r=alexcrichtonbors-11/+99
Musl host toolchain Based on https://github.com/rust-lang/rust/pull/55163 and https://github.com/rust-lang/rust/pull/57359 Depends on https://github.com/rust-lang/rust/pull/55566 CC https://github.com/rust-lang/rust/issues/57439 ### How it works Tested compiler made by `dist` on glibc and musl based distributions and verified binaries it produces: * Ubuntu (glibc) - installed it as a target for host toolchain and observed no regressions for static (default) linking, dynamic linking apparently requires musl build libgcc so I didn't test it. * Alpine (musl) - installed as the host toolchain, by default it links statically (executables are portable and work on glibc distributions) but with `-C target-feature=-crt-static` Rust flag it links dynamically (executables require musl built libraries). ### What's debatable It should be decided whether this toolchain should link dynamically or statically when using it on musl distribution. I believe the distributions would prefer dynamic linking but it'd be misleading because `$ARCH-unknown-linux-musl` target links statically on the other hosts. Another problem is using `RUSTFLAGS='-C target-feature=-crt-static'` for dynamic builds which is really uncomfortable. To address both issues I suggest leaving `$ARCH-unknown-linux-musl` static for both host and cross target and introducing "alias triple" `$ARCH-unknown-linux-dynmusl`. It'd be the same as `$ARCH-unknown-linux-musl` (and use the same libraries to avoid duplication) but it'd link dynamically. <del> ### Why it's still WIP (help wanted) I'm having a hard time getting all tests to pass and I'd appreciate help.
