or it would be if the elf weren't demented.
one of those scary ones.

5c/5l code will run on arm 9 (there are possibly some
extensions in arm 9, and if so, they won't use them,
though even that is usually easily dealt with).

possibly the bigger complication is the extent to
which the output is PIC enough (or can easily be
made so) for this application.  i remember looking
at an ARM application note about that but just
remember my resulting dismay, not what caused it.
it might not have been the PIC conventions as
such but its interaction with something else.

as to that ELF, is the loading program expecting
a completely linked program or something that
is then linked dynamically into one already running?
if the former, the existing ELF-header producing
code might well suffice (with the usual changes
to account for dementia, hence some of the "??"
in comments in existing code); if the latter, you'd need
to convert the symbols as well, and perhaps capture
and convert data for relocation (which isn't normally
produced except for dynamically-loaded modules).
i'm assuming you're safe from the elf's mate, a sly dwarf.
