This is the only linux target missing in the dist builders.

Thanks! I'm surprised it worked as-is :)

Out of curiosity, is this a target you're planning on using or is this mostly just for completeness?

CC and CFLAGS are missing (rust-lang/cc-rs#271)
It worked locally, I'm trying it on travis.

Just for completeness 😄.

It worked on travis too. The last commit removes the try from .travis.yml

Ok, we can always continue to iterate on it I think as well!

Interested in this for use on a Lego EV3. Able to build a hello world just fine but I get an immediate segfault running it on the device or on QEMU.

@green-s I also get segfault when running in qemu... I made some mistake, because I thought I got it working before making this PR... Sorry, but I cannot take a look at this now.

Remove armv5te target from dist-various-1

Reverts rust-lang#46498

I must have made some mistake when I tested that commit and thought
armv5te target worked. but testing it now the produced binaries
segfaults
(rust-lang#46498 (comment)).

I tried using crosstool-ng and buildroot toolchain (for armv5te) but
the produced binaries also segfaults. Maybe there is a issue with the
target, but I cannot investigate it any further.

I think the best for now is not to distribute the armv5te target.

I'm sorry for what happened.

Today I tried rustc 1.24.0-nightly (8503b3ff8 2017-12-04) and produced binary from such simple code segfaults:

fn main() {
    let mut f: f32 = 1.5;
    println!("test: {}", f);
    f = f * 1.4 + 1.3;
    println!("test: {}", f);
}

it crash in __sync_val_compare_and_swap_4, almost all other examples of code also crash in this place.

But the same code compiled by rustc 1.23.0-nightly (ee2286149 2017-11-07)
run without any problems and produce expecting results. So it is some kind of regression in code generator.

Codegen seems fixed in the latest nightly. Is this ok to be resubmitted?

Add dist builder for armv5te-unknown-linux-gnueabi (again)

The dist builder was first add in #46498 and later remove in #46498 because of #46822.

#46822 seems to be fixed now (I and @green-s have [tested](#46498 (comment)) it).
