Some linker situations able to crash a simple C++ program

Description
On attempt to compile a simple C++ hello world with iostream, one can cause a mix of c++ libraries which crashes before reaching main. It's based on the situation of a build using hpkg libraries and pkg-config.
Example
This works: g++ -std=c++11 -o hello hello.cc && ./hello
But this crashes:
g++ -std=c++11 -o hello hello.cc pkg-config sdl2 libuv uchardet --libs
&& ./hello
The trouble makers are -L
flags expanded by pkg-config, which add a path containing a libstdc++.a static library.
The two tests show different readelf -d hello
output.
The working case indicated a dynamic link with libstdc++.so, the crashing case does not.

This seems to just be a bug in our GCC or libstdc++ ports, so please open a ticket at https://github.com/haikuports/haikuports instead of here.
I don't think we should ship a static libstdc++ at all, probably (or at least not in a default search path.)
