We track this bug report under https://linaro.atlassian.net/browse/GNU-1625. Please let us know if you have a fix.
I know what's wrong, will fix in a couple of hours.
The definition of choose_pool_size needs to be moved outside the preprocessor group guarded by #ifdef _GLIBCXX_HAS_GTHREADS
It should be fixed at r16-2123-g7a878ba615c2c5
If you have any questions regarding this report, please ask on linaro-toolchain@lists.linaro.org mailing list.
