Buildroot has historically had the busybox version selection maybe
because of it's origins.
I agree we should at least ditch the older versions since other than a
'stable' and 'experimental' there's no more reason.
With that being said now that toolchain components are packages we do
have multiple versions :) Granted it's something special.

We could kill the baseline, say 4.2.x (with avr32) and 4.3.x, and go
Which sparks the SPARC question, LEON is supposedly the best and only
target for any meaningful usage these days, qemu sparcstation is just a
testing ground for the architecture (doesn't quite work right with the
latest bits though, networking including loopback is broken, haven't dug
into what's the exact component causing it, may very well be qemu itself
doing something bad in the latest versions, it happened before).
Blackfin yeah i did the internal toolchain fixes up to "it builds and
looks ok" - if that works is a whole different matter, i've got 0
hardware to test it and 0 feedback, it may mean anything.
For PowerPC there are some issues with gcc 4.9.x, 4.8.x is good so no
Question is, how far are we going to keep architectures 'alive' without
