Iain, I have no input data to build a theory upon it. (And I am pretty sure that the next ten years *I* won't learn GCC's build rules – I am only an average, and old, guy.) All I have is the obvious: the database of rules 'make -p' prints out shows that make has knowledge of the three missing files (or rather symlinks). Make's debug output has forgotten it. Why? Is make buggy? How many makes (versions) are so buggy? Maybe I did not express it that way: GCC-15.2 and GCC-16.1 do build. Due to manual intervention the build finds its final stage. Are more proofs needed? In seven or eight days I'll have a version of GCC-16.1 based on your patch files running. And testing, I hope. Do you want to suppose a particular set of configure arguments before I start?
