As reported previously, I had this issue when I used my 2010.02 buildroot,
kernel and busybox .config files with 2010.rc1 and just accepted the default
options for missing configuration items.  However if I regenerated my
.config from scratch using 2010.05 rc1 menuconfig (selecting all the
same/equivalent options) then this build issue went away

I think it is this update of uclibc options that is the problem.  I have not
examined the differences and dug deeper to resolve but you might like to ;)

I also asked the list if carrying forward .configs like this was an
acceptable way to move to newer versions of buildroot - it would seem at
least you and I are doing it!
