--- Comment #1 from Yann E. MORIN <yann.morin.1998@free.fr> ---
Bilge,

The coreutils buildsystem detects features of the toolchain, and
generates "accessors" to various internals. UT_USER is an accessor
to fields of the utmp (or utmpx) structure.

Your toolchain lacks this structure or this field in this structure.

You have to realize that uClibc is configurable, and if you configure
it with very few features, then things will start to break.

Fix your toolchain, or use a pre-built one.

Regards,
Yann E. MORIN.

--- Comment #2 from bilge at scriptfusion.com ---
Hi Yann,

Thanks, I believe your analysis is exactly correct: I am missing utmpx, but not
because I deliberately disabled it; that feature is disabled by default in
uClibc 1.0.9. However, I'll be sure to enable it now!

Thanks,
Bilge.
