The intel hex file format for can handle files larger than 64k. There
is an "extended linear address record" which is used to change the
address if it exceeds 64K (the 16-bit limit). It's not pretty, but it
works.

I would imagine that binutils would handle this properly. If that's
not the case, it's a bug in binutils (or more precisely, bfd) that
should be fixed.

I vaguely remember doing some tests when fixing uisp to handle ihex
files > 64K and avr-objcopy worked at the time. Although, that was a
while ago.
