  Log Message:
  -----------
  [ubsan] Link shared runtime library with a version script.

Summary:
Do not reexport libgcc.a symbols and random sanitizer internal symbols
by applying a version script to the shared library build.

This fixes unwinder conflicts on Android that are created by reexporting
the unwinder interface from libgcc_real.a. The same is already done in
asan and hwasan.
