Why is 64k? It is 16bit relocation. You should be able to go both
directions.

# cat foo.s
.extern bar
.global foo
.code16 
foo:
jmp bar 
# cat bar.s
.extern foo
.extern xxx
.global bar
.global yyy
.code16 
bar:
jmp foo 

yyy:
jmp xxx
# cat xxx.s
.extern yyy
.global xxx
.code16 
xxx:
jmp yyy 
# cat pad.s
.space 0x7ff0
# ld -Ttext 0 -e 0 foo.o pad.o bar.o pad.o xxx.o
