Auto merge of #78142 - operutka:armv5te-unknown-linux-uclibcgnueabi-target, r=petrochenkov
Add built-in support for the armv5te-unknown-linux-uclibcgnueabi target Hi! I'd like to add built-in support for the `armv5te-unknown-linux-uclibcgnueabi` target. It's a pretty common target used by many devices like routers and IP cameras. It's mostly a copy-paste of `armv5te-unknown-linux-gnueabi`. I've tested it on a quite complex application that uses tokio, openssl and a lot of other stuff and everything seems to be working fine. I'm not sure about the `post_link_args` but the point is that my linker fails when `-ldl` isn't specified. Maybe there is a better place where to put this option... It's my first contribution to Rust itself, so feel free to wash my head :smile: _Note: The app mentioned above was built with this in my `.cargo/config`:_ ``` [unstable] build-std = ["core", "std", "alloc", "proc_macro", "panic_abort"] build-std-features = ["panic_immediate_abort"] ```
