### What does this PR try to resolve?

Try to promote the following [[Tier 2 without Host Tools](https://doc.rust-lang.org/rustc/platform-support.html#tier-2-without-host-tools)](https://doc.rust-lang.org/rustc/platform-support.html#tier-2-without-host-tools) targets to [[Tier 2 with Host Tools](https://doc.rust-lang.org/rustc/platform-support.html#tier-2-with-host-tools)](https://doc.rust-lang.org/rustc/platform-support.html#tier-2-with-host-tools):

- `aarch64-unknown-linux-ohos`
- `armv7-unknown-linux-ohos`
- `x86_64-unknown-linux-ohos`

### More Information?

see MCP: https://github.com/rust-lang/compiler-team/issues/811

### Blockage to be solved?

- [x] Submit an MCP
- [x] Submit code of promote ohos targets
- [x] Resolve related dependencies （`measureme`）

The modified code of the measureme has been merged （see https://github.com/rust-lang/measureme/pull/238）. [done]

+## Requirements
+
+All the ohos targets of Tier 2 with host tools support all extended rust tools.
+(exclude `miri`, the support of `miri` will be added soon)
+
+### Host toolchain
+
+The targets require a reasonably up-to-date OpenHarmony SDK on the host.
+
+The targets support `cargo`, which require [ohos-openssl](https://github.com/ohos-rs/ohos-openssl).
+
+`miri` isn't supported yet, since its dependencies (`libffi` and `tikv-jemalloc-sys`) don't support
+compiling for the OHOS targets.
+
 ## Setup
 
 The OpenHarmony SDK doesn't currently support Rust compilation directly, so
