I've experienced the same problem twice (sparc and x86 arch). Removing the redirection to /dev/null for the test in the ebuild, I read the error message from gcc-config which wasn't able to find gcc... So it may be a gcc-config compatibility problem or an environment variable problem. I ran : emerge -v --oneshot gcc-config etc-update env-update source /etc/profile ... and glibc is now building fine with nptl support.
This should be fixed in the toolchain.eclass update (properly running gcc-config after the emerge).
