- Makes the default behavior of on-device building with the address sanitizer match the default behavior of building with the address sanitizer on Clang for Desktop Linux distros, which is to use the static library
- Fixes https://github.com/termux/termux-packages/issues/26485
- On devices that do not have `libclang_rt.asan-$arch-android.so` or which have a corrupted one, fixes building on-device with `-fsanitize=address`

```
- After: believed to work
