Rust failing to compile and build on OS X 10.9

[Porkepix]

Rust is supposed to support OS X up to version 10.7.

While it was possible to compile it on 10.9 until version 1.24.1, versions 1.25 and later would not compile anymore using Homebrew formula.

Here are errors:

This output in when trying to install through Homebrew.
Even if I used RUST_BACKTRACE=1 on the line, it didn't seem to change the output probably because ran through Homebrew.

In case it would provide more informations, I also ran by hand the build from 1.26.2 sources, here's the output:

It's also failing, even if I'm not sure the issue is quite the same.

FWIW, if anyone encounters this issue themselves and just wants to get Rust installed, the packaged installer at https://static.rust-lang.org/dist/rust-1.30.1-x86_64-apple-darwin.pkg (via https://www.rust-lang.org/en-US/other-installers.html) installed and ran okay on a OS X 10.9 machine.

May also be relevant for #50776.

It would still make fail the dependencies resolutions for Homebrew's package depending on Rust though.

Update: FWIW can confirm https://static.rust-lang.org/dist/rust-1.42.0-x86_64-apple-darwin.pkg (via https://www.rust-lang.org/en-US/other-installers.html) installed and seems to run okay on a Mac OS X 10.9 machine.

Closing, presuming to be a duplicate of #50776.
