termux-pacman-bot 9b1d8bc03e fix(main/clang): default to using the static library of the address sanitizer instead of the shared library
- 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`

- Samsung Galaxy S III SPH-L710 with LineageOS 14.1 Android 7.1.2 before:

```

- After:

```

- Vivo iQOO Neo8 V2301A with Android 15 before:

```
thread #1, name = 'a.out', stop reason = signal SIGILL: illegal opcode
```

- After: believed to work
