Unfortunately in the beginning of the current toolchain development cycle
we decided to stay on uClibc-ng 1.0.17 + backported ARC-related patches
due to different reasons and given we're now on rc2 stage there's no chance
to switch to any other version unfortunately. I hope next dev cycle we'll use just
latest upstream uClibc-ng release.

In other words (1) won't happen in coming days.

We're talking only about __prebuilt__ ARC toolchain right?
Because Buildroot-built tools use latest uClibc-ng with correct config.

Ideally I'd prefer to update affected packages so they are disabled for
ARC prebuilt tools with some easily greppable comment like:
----------------->8-----------------
 xxx yyy zzz # arc_prebuilt lacks wordexp
----------------->8-----------------
that will help us to track missing parts we need to work on in the future.
Otherwise we may just disable autobuilder for ARC prebuilt tools because:

1) There's no such thing as prebuilt engineering builds i.e. autobuilder
   only will test either RCs or final releases of ARC prebuilt tools which
   IMHO makes not much sense as that's a bit too late, rgiht?

2) We know there're differences in ARC prebuilt tools from what gets built in
   Buildroot still having ARC prebuilt tools is a nice opportunity to
   simplify life for some people who prefers to not build toolchain
   themselves and for basic stuff it usually works quite fine.
