This is a tricky problem to solve, and I suspect what you're doing
here is not correct in general, even for a single input section.  For
example, what happens if the output section statement specifies
alignment?

I've faced something similar before on ppc64 with stub sections, and
the solution I found was to create the section with minimal alignment,
then increase to the desired alignment when the section is found to be
non-empty.  That idea might work for you too.
