The kernel configuration seems to be malformed:
[...]

UID16 is set, but...
> # CONFIG_MULTIUSER is not set
And quoting init/Kconfig:
config UID16
bool "Enable 16-bit UID system calls" if EXPERT
depends on HAVE_UID16 && MULTIUSER
That dependency exists precisely because this error would occur if it
didn't.
The only thing I can think of that might not respect that dependency
would be a "select UID16", and I don't see any of those either in the
current tree or in the tree as of that commit. So I don't see any way
this can have legitimately occurred. How was this kernel configuration
generated?
