The hardware costs money, but it's the only thing in that list which
you are forced to pay money for.

gcc/binutils/gdb, as well as been a native toolchain, is also a cross
compiler capable toolchain.

RTEMS provides support for using Ada on ARM boards (if you are willing
to run under a RTOS instead of bare metal) and there are plenty of
example BSPs in the RTEMS source kit for you to use as a template for
your own BSP.

If you want true bare metal, then there is a port of GNAT for AVR.

So, while the embedded options for Ada with gcc are not nearly as
numerous as those for pure C, they do exist.

Someone here in c.l.a has also done some work on making GNAT run on
bare metal ARM boards. I do not know the current status of that work.

Simon.
