An exported global variable that points to the head of the
PyInterpreterState linked list (i.e. the return value of
PyInterpreterState_Head). This way my program could just look this up
from the dynsym section instead of scanning a dump of the bss section
in memory to find a possible candidate. It would be grand if also the
string in the rodata section that gives the Python version could be
dereferenced from dynsym, but that's a different question.
