Right on the nail!  Indeed, this causes the bug to show up.

Yep.  I'll keep looking for something else for a while :-)

I managed to reproduce the problem with the following pair of assembly
files:

.text
	nop
	nop
	nop
	nop
.text
	.long bar
bar:

Generating a shared library out of them like this causes relocations
to be correct:

ld -shared t.o v.o -o tv.so

but creating an intermediate relocatable object file breaks them:

ld -r t.o v.o -o w.o
ld -shared w.o -o w.so
