For me, the ld complaints are completely opaque. Can you give me a
clue how you go about figuring out where the complaint is coming from?

This is what I get with UML/x86_64 with rc6-mm2:
WARNING: vmlinux - Section mismatch: reference to .init.text:huft_free from .bss between 'stdout@@GLIBC_2.2.5' (at offset 0x6027b748) and 'completed.6111'

gdb tells me:
(gdb) x/4xa 0x6027b748
0x6027b748 <stdout@@GLIBC_2.2.5>: 0x0 0x0
0x6027b758 <completed.6111+8>: 0x0 0x0

So, with stdout@@GLIBC_2.2.5 at 0x6027b748 and completed.6111 at
0x6027b750 - right next to each other - there would seem to be nothing
between them to reference anything.

In any case, with bss containing zero-initialized stuff, I don't see
how anything here can refer to anything anywhere else.

I see one (the one quoted above). Thanks for adding .plt - that made
the build much more pleasant.
