Hmmm. I see. I need to also generate multilibbed versions of
crtbeginS.o and crtendS.o. That's slightly annoying, as I was hoping
to get rid of them, but I guess not.
Wait. I don't see. How is this really supposed to work? It seems to
assume a limited model of the execution environment, in which each
process holds exactly one object which is not compiled with -shared;
this is not a safe assumption, as both the all-shared-object and
multiple-nonshared-object cases can occur (the first more frequently).
