Generally it is, but OE is being used for not-really-embedded systems
too like the Sharp Zaurus (which is more of a handheld computer) and
the ipaq. AFAIK, OpenEmbedded, Angstrom, and Familiar all use glibc.

Is there a specific reason you need a new version?

Perhaps you can try building from svn. I do see a uclibc_svn.bb in OE.

OE still has support for uclibc, I'm not sure why you think that it
doesn't. It also has support for glibc and is being used, IIRC, to
build both uclibc and glibc. OE doesn't "use" either, it support both.

Sorry, I don't know that one.
