Issue: [bug] Android build on Arch Linux: 'getentropy' is unavailable: introduced in Android 28
Labels: type: bug,status: needs triage

### Describe the bug

I used reqwest in the project and needed to compile it to Android, but reqwest relies on 'opensl-sys', which reported an error when compiling Android.
`When compiling Android "openssl-sys" read the"aarch64-linux-android24-clang" version, but we followed the error message and requested to use a version higher than 28.
Therefore, if the CC variable is passed separately when compiling "opensl-sys" for Android, it can be successfully compiled, for example, “CC=$HOME/Android/Sdk/ndk/28.0.12433566/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android35-clang cargo build -p mobile --target aarch64-linux-android”，
But passing CC variables during Tauri compilation doesn't seem to take effect? Or are there any other solutions?

### Reproduction

_No response_

### Expected behavior

I hope to compile it into an Android app in archLinux.
