Read the rest of the thread; it's clear from context. We are talking about
ways to get Ada running on boards way too small for Linux. Usually that's
a bare metal mode, but RTEMS may be a option for the more capable of these
small boards/MCUs.

It's clear from the next paragraph I am talking about cross compilers.
However, just to make it clear:

What is needed is to create a Ada compiler which will create code which
runs in bare metal mode on a number of specific architectures (ARM and
MIPS would be my personal initial preferences).

At this point, I'm beginning to think you are either trolling or just
refusing to accept (for whatever reason) that there's a vast embedded
market out there, outside of what you are used to, which could be a
target for Ada.
