Indeed. :)

That's why, for instance, the _rel_dyn_start_ofs literal is defined as

.word _rel_dyn_start - _start

... rather than simply as

.word _rel_dyn start

... because the latter always produces 0 (it expects it to be fixed up
by the relocation code, which causes a catch-22) while the former
produces the expected difference which can then be fixed.

Yes, it baffled me too. :)
