Depends on what you mean by processed. Yes, they are parsed and
converted to internal format before open_output, but why does it
matter? Nothing much depends on maxpagesize until
lang_size_sections.
Perhaps even a nicer patch would be to put your
bfd_emul_set_maxpagesize calls in a LD_EMUL_SET_OUTPUT_ARCH hook,
which is called just after open_output.

Why can't you use output_target?
