The autobuilders are now doing fully random testing I believe, so they
are no longer testing some of those "special toolchains" we used to
have. They are either using well-known external toolchains, or building
internal toolchains.

In any case, I don't think we should worry too much about uClibc
features, and assume that people should have a recent uClibc, with the
uClibc configuration as it is in Buildroot.
