I don't mind bumping binutils and gcc. For now, that newlib snapshot is OK
but I think we may want to bump to a newer one to catch the added POSIX
methods from Aditya.

What concerns me is: https://devel.rtems.org/milestone/4.12.0 which still
shows 80 tickets and I still don't think there is one describing the x86
breakage on libbsd. I have no idea how many of those should be addressed.
These should be evaluated rather than just kicked down the road.

I did a build sweep with fresh tools yesterday. All BSPs built in my
configuration and the warnings are in OK shape. I have filed some tickets
about a few but most of these are very easy to fix for the right person.
Here are some areas by person who could fix quickly. Out of 57 unique
warnings:

+ 12 are in libdebugger(Chris)
+ 6-8 are in BSPs or termios that I think you need to look at.
+ 7 are in new mmap code (Gedare)

It would be great if the core developers could take a look at the full
report and see what can be eliminated

There are somie warnings for the static asserts. I suspect these are due to
BSPs are low optimization levels.

So I would like to make sure we:

+ know the state of all tickets and consciously make a decision on them.
+ address some of these warnings.

That doesn't begin to address whether BSPs work or odd issues like do we
switch to Couverture for qemu.

I'm not trying to be an impediment. I just want a burn down list.
