    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.
