  You mean the sentinel entries (leading 0xffffffff, trailing 0x00000000)?  I
don't quite get this; where would they go?  The test in question uses -Ur with
a relocatable link.  I don't understand how it's supposed to work; if we merge
the .[cd]tor sections and build the lists and ap-/pre-pend the sentinels, the
generated object won't be truly relocatable - as indeed that's what we do, and
we fail when further static [cd]tors are added in the final link and they
don't all get processed.  Are we just supposed to preserve separate
.ctor/.dtor sections, but build the final form of the lists in them?  That
doesn't seem like it would work right either.

    cheers,
