Apparently this was applied against gcc-16:

https://tracker.debian.org/news/1776755/accepted-gcc-16-1610-3-source-into-unstable/
   * Enable LRA by default on m68k for snapshot builds (Adrian Glaubitz).
     Addresses: #1142039.

https://buildd.debian.org/status/fetch.php?pkg=gcc-16&arch=m68k&ver=16.1.0-3&stamp=1785220565&raw=0
  Applying patch m68k-lra-enable.diff
  patching file src/gcc/config/m68k/m68k.opt

I suspect this might be the reason why gcc-16 16.1.0-3 started to FTBFS 
on m68k.
