With .rodata being in FlashROM now, gap can be much smaller now. InstRAM can be max 32K, and with segment headers, that already makes it more than 32K. Then there's some .data still, and the next Flash page boundary is 0x9000. That figure should be more or less future-proof. TODO: Refactor makeimg to take FlashROM segment offset from file name.
