Applied, thanks.

Alexey, could you please enable UCLIBC_HAS_LIBNSL_STUB=y in the uClibc
configuration used for the ARC external toolchains? Generally speaking,
if you could have a look at the differences between the uClibc
configuration you're using, and the default Buildroot one, it would be
useful. We cannot support all the little variations of the uClibc
configuration, so if you could use a configuration that is at least a
super-set of the features enabled in the uClibc configuration used by
default in Buildroot, it would really make things easier.

Thanks a lot!

Thomas
