Now analysed. The ppc64le kernel problem is due to needing to keep
undefined symbols. I'd say it is also a kernel bug that the symbol in
question isn't defined, but that's really another issue. The point is
that we have a GNU ld use case where removing undefined symbols breaks
an existing program.

I'm of two minds about this. PR3417 wants undefined symbols to be
removed: "When the reference to __tls_get_addr is removed, it leaves
undefined symbol in symtab. It is confusing." H.J. what exactly was
confusing? When I made the PR3417 patch, I thought PR3417 was mostly
about cosmetics and figured that removing undefined symbols was
reasonably safe. If it is true that PR3417 was only cosmetic, I think
my patch ought to be reverted.
