I must admit that I hadn't really thought through the implications of
having an Fcode bootblock.

I still think that linking in loadfile_elf64.o is the correct short to
medium term solution. It isn't perfect, but it is consistent with the
current loadfile design. I don't have a problem with someone coming up
with a better design, but nobody seems to be in a hurry to fix the
implementation of the current design.
