I think the newlib toolchain was only intended to be used as part of www-client/chromium's build process and not for developing nacl apps (for that glibc toolchain is intended I think, which we don't package in Gentoo). nacl packaging is pretty bad at this moment, nacl support in www-client/chromium has been dropped because it also requires pnacl now which is non-trivial to package.
(In reply to Paweł Hajdan, Jr. from comment #1) please tweak the DESCRIPTION then so people don't expect anything else
