Is it possible to define this in the RTEMS Ada glue file?

Generally, I like the Ada support to be self-contained and
have no impact on anything else. This puts an Ada specific
variable in generic code.

This is similar to how I had to do the Ada task minimum
stack size. It could have gone in more common code but
nothing else uses it so should not be impacted.

Plus newlib doesn't know anything about our Ada glue layer.
Best to keep it that way.
