I don't understand your point. RTEMS is an OS.

Not you, nor the customer. Who then?

A compiler cannot run on bare metal. You need a GCC cross compiler to be
able to do something like

   gcc -c -march=armv7 foo.adb

on the host machine.

I don't think that would be very difficult, but, as I said in this
discussion already, I would be quite useless unless you say what of the RTL
goes over the board and what stays.
