Primary issue to me: Newlib's lack of API/ABI stability.

To many changes. That said, I do not see any perspective for an RTEMS 
release unless there are, say at least 2 months without newlib receiving 
RTEMS-related changes.

In case somebody wonders, why I haven't upgraded newlib in my toolchain 
packages: The churn the RTEMS submissions are causing have become 
unprocessible to me.

IMO, it's time to pull the plug out of some targets.


- the avr, lm32 and m32c target should be discontinued, because the 
corresponding toolchains are in rather unusable shape with no 
improvements in sight.

- the sh and h8x also seem to be candidates for discontinuation.
At least I don't see a viable userbase of them.

My opinion: Not ready, postpone after 4.11.
