+# `armv5te-unknown-linux-gnueabi`
+
+**Tier: 2**
+
+This target supports Linux programs with glibc on ARMv5TE CPUs without
+floating-point units.
+
+## Target maintainers
+
+[@koalatux](https://github.com/koalatux)
+
+## Requirements
+
+The target is for cross-compilation only. Host tools are not supported.
+std is fully supported.
+
+## Building the target
+
+Because this target is tier 2, artifacts are available from rustup.
+
+## Building Rust programs
+
+For building rust programs, you might want to specify GCC as linker in
+`.cargo/config.toml` as follows:
+
+```toml
+[target.armv5te-unknown-linux-gnueabi]
+linker = "arm-linux-gnueabi-gcc"
+```
