See
<http://www.gnu.org/prep/maintain/html_node/Copyright-Papers.html>. To
use anything based on the 2009 work, either Nokia will need to complete a
corporate copyright assignment for that work, if it is copyright Nokia
pursuant to whatever employment contract Siarhei Siamashka had with Nokia
at the time, or Nokia will need to complete an employer disclaimer and
Siarhei Siamashka will need to complete an individual assignment. And the
same applies for anyone else who has made significant contributions to the
code.

I suggest raising such a question of configure options for such trade-offs
more generally on libc-alpha.
