googlecloudprofiler breaks other packages which depend on C++ code compiled against a different version of libstdc++

These lines here,

statically link this package's native code against the particular version of libstdc++ available at link time. This breaks other packages which have native code and depend on a different version of libstdc++.

It seems reasonable to me to ask your users to have a recent version of libstdc++ and libgcc available. Or perhaps you could publish two packages to PyPI, this one and one that uses a dynamic link?

Thanks!

PS: I discovered this because version 4.0.0 is [incompatible with libsass](https://github.com/sass/libsass-python/issues/413).
