Can you save the out/ directory from both builds and "diff -ur" them
(maybe just the *.lds files)?

I'm noticing that pathnames are embedded in some ELF section names (I
hope this sentence makes sense), and when you build at d75c22fc, those
pathnames contain dot-dot (".."), ie. two section name separators next
to each other. Maybe that's not good; no idea.
