I would prefer to see this bootstrapped and only for 12.0

Please, land before D18427 if you plan to MFH to 2018Q4.

lang/rust builds on 12.0-RC3, but I have a problem building devel/rust-cbindgen.

error[E0412]: cannot find type `c_long` in the crate root

Is the built rust compiler 100% functional? This port builds on amd64.

@pkubaj_riseup.net, bundled libc-0.2.41 doesn't support powerpc* on FreeBSD. Which version does or which part do you need backported?

libc crate is used by pretty much every lang/rust consumer. If you don't land powerpc64 support upstream maintaining patches in consumers with vendored dependencies (e.g., net-im/fractal, www/firefox) is going to be hard.

Currently there's no support for any powerpc* on FreeBSD (https://github.com/rust-lang/libc/tree/master/src/unix/bsd/freebsdlike/freebsd).

I guess it's better to fix lang/rust alone for now and then take care of libc. Fixing lang/rust will make it much easier to fix other Rust-related ports because of no need to bootstrap on other architecture.

What is needed for this to be moved along?

A rebase after recent changes and a promise to attempt to upstream the libc crate and other patches.

I've just copied the bootstrap files to LOCAL/tobik/rust, so please add it to MASTER_SITES for {rust,cargo,std}_bootstrap too.

I can try to submit my patch upstream if they accept non github submission. It'll also be easier for me if all the aarch64 patches are submitted first.
