  Log Message:
  -----------
  libcxxabi: declare __gnu_unwind_frame in cxa_personality (#189787)

ARM EHABI builds of libcxxabi fail with clang-22+ because
cxa_personality.cpp calls __gnu_unwind_frame without a visible
declaration, triggering:

  error: use of undeclared identifier '__gnu_unwind_frame'

Add an extern "C" forward declaration before the EHABI unwind helper so
the source compiles correctly.
