Looking further into this I'm beginning to think that the previous
behaviour was a bug that has since been fixed (and that probably has
nothing to do with the DWARF5 sections other than this change for some
reason interacted with the pre-existing bug to trip up a poorly written
autoconf test in gnulib).

In fact it appears that with 2.38 weak symbols are in fact working
correctly for the handful examples that I've come up with.  I'll have to
go back to the original example that produced buggy behaviour (grep-3.7
w/o patched gnulib threadlib.m4) and see if that's now working as well
(it may not, since the libraries have all been produced by earlier ld,
but it seems worth trying).


Regards,
Achim.
