Revision http://gcc.gnu.org/viewcvs?view=revision&revision=189772
added constant Support_Atomic_Primitives to the target specific
system-*.ads files. The default system.ads was not updated.

The included patch
- adds the missing constant
- removes constants not present in other system-*.ads files any more

This patch is NOT ok, system.ads is a special version, used for bootstraping
the compiler, and as such, has different constraints.

There is nothing to change here.

It is however used when building libada if target specific version is not specified
in gcc/ada/gcc_interface/Makefile.in. In that case building libada fails due to missing
Support_Atomic_Primitives.

Well, then you should submit changes for Makefile.in for your
unsupported target. That being said, see below:

Yes, this is a known issue, see PR 54125.

The fix is coming soon, and is quite different from your patch.
