Correct. Contrary to what Rob said, we (Buildroot) have only added
support for Musl, not switched to it as our default C library. We
actually discussed switching to glibc as the default C library, but
never to musl. We want to offer the option of using musl, but for the
moment not as the default. Also our musl support is still experimental,
and there are lots of packages in Buildroot that do not yet build with
musl.

However, we are indeed quite desperate about the state of uClibc and
the lack of stable releases. Which is why I've personally encouraged
Waldemar to do the uClibc-ng project, Buildroot offers the option of
using uClibc-ng, and I will propose to make that the default C library
choice in the next Buildroot release.

At this point, I don't think there's any hope for uClibc to ever do a
release.
