Probably so.

Well we may do a full side-by-side comparison of uClibc's defconfigs
but that barely makes a lot of sense. I mean we used to use some configuration
which was formed as it was in years and not all choices I may justify and explain.

Still we're slowly drifting to Buildroot's uClibc defconfig with pretty much every
our release but not yet there... and Buildroot's defconfig changes with time but
we cannot change ours in the middle of development cycle.

Again we may do that comparison and identify all [meaningful] differences
but not sure what it gives.

Well we used to have ARC prebuilt toolchain in autobuilder if I'm not mistaken.
But due to some significant deviations from Buildroot defaults like missing IPv6
back in the day it got nuked. Maybe Thomas can remember it better... for some
reason I cannot find any signs of ARC prebuilt tools in
https://git.busybox.net/buildroot-test/?so I might be wrong here.

But indeed we wanted to get some more testing for that pre-built toolchain
and catch a couple of issues before cutting rc2 and final release.

And essentially once and if that patch gets accepted the plan was to
submit a config-fragment for it.

Good catch - we'll fix that.
