Unfortunately, I'm not familiar with the `-static` option and didn't manage to find what exactly it means. Why this option is required here, maybe it applies by default? I see `BC->IsStaticExecutable` in the check you introduced, do they, the option, and the variable's value related? Is `IsStaticExecutable` set to `true` for binaries statically linked with the glibc?

Thank you.
