I think you might have misunderstood my report: I did not say that the
toolchain failed to build (since it's a pre-built toolchain!) but that
the toolchain is not capable of building gdb, weston and civetweb.

And all those changes in the 'master' branch of uClibc are regularly
merged in uClibc-ng. So basically uClibc-ng is *everything* that uClibc
has, plus much better testing, and regular stable releases.

In Buildroot, we currently support both. Our plan is to use uClibc-ng
as the default uClibc version in Buildroot 2015.08, and if things
continue to go well with uClibc-ng, deprecate old uClibc completely.
