yeah - this was the only thing that i had any specific guess
about, i haven't tried gcc 16 yet.

would be really nice if someone updated the ctf tools -- the
upstream one supports dwarf5 i understand, but this should
not really matter for gcc 16 -- same as it shouldn't have
(and seems to not) mattered for gcc 15, etc.

as a random hack, try forcing "-gdwarf-5" into HOST_CFLAGS,
which would make the stage1 compiler use the same defaults..
