Subject: [PATCH] fix: remove static libstdc++ linking on Linux to prevent
 potential crashes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Unity on Linux is dynamically linked against the system's libstdc++.so.
Statically linking libstdc++ in a native plugin caused runtime
mismatches, leading to crashes when destroying C++ standard library
objects.

This was observed with local std::stringstream instances, but likely affects other STL types relying on shared runtime state (e.g.
std::locale, iostreams, allocators).

Switched to dynamic linking of libstdc++ to ensure compatibility with
Unity’s runtime environment.
