Hm, you're right.  The cases I looked at appeared to be adjacent, but
it's not actually sorting.

I guess a combination of both changes is best -- the `combreloc'
change basically costs nothing, and does actually help a bit even
without direct ld(1) support (c.f. all the __pure_virtual lookups it
elided completely).
