As the error states, he *is not* running it as root. Moreover, running 
as root IS NOT RECOMMENDED - crosstool-ng is quite explicit about it.

The problem is that he took a config from 1.22 and tried to run it on 
master without upgrading it through the regular procedure for 
kconfig-based system ("oldconfig"). In master, build directory is set 
using a value of an auxiliary variable, CT_BUILD_TOP_DIR, that isn't set 
in the config unless it is upgraded.
