 Runtime loader is also a shared object. However, it doesn't really matter
 what is the value of `__dso_handle`, only its address is important.

 BTW I don't really see why we would need to explicitly set `__dso_handle`
 to zero or how such explicit initialization would move it from .bss to
 .data. Static and global variables are by default initialized to zero.
