The problem is that crtstuff generates, in the `.init' section, when
not !defined(OBJECT_FORMAT_ELF), a function prologue in crtbegin.o and
an epilogue in crtend.o, which duplicate crti.o and crtn.o.  Also, it
doesn't define `_init' and `_fini' symbols, as expected by crt1.asm.
Also, it apparently wouldn't generate a `.fini' section.

I tested several combinations, and ended up deciding to revert the
patch for COFF.  I might give it another try further down the road.
