The Arm Compiler (armclang) toolchain replaces standard library calls
like `snprintf` with renamed versions such as `__2snprintf` in
generated object files and binaries. This name mangling is part of
armclang’s internal handling of standard functions and can lead to
undefined reference errors if these symbols are not defined.
To resolve this, this patch introduces a new assembly stub for
`__2snprintf` in AArch64-specific implementation.
This stub is a minimal alias that branch directly to the
underlying `snprintf` implementation. This mirrors the existing
solution for `__0printf`, `__1printf`, and `__2printf` aliases that
redirect to `printf`.
