Position independent CODE with position dependent DATA ?

If the generated code is that stylized, then another option is a utility
program which takes a .o, finds those two-instruction sequences, then
re-writes the code in-place to become:
-----
> 80018098:	4b 16       	lddpc	r6,8001815c    <-- R6 = 0x4000
> 8001809a:	XX XX       	<<two-byte NOP>>
> ... do something with GOT...
> 8001815c: .word        0x4000
