This is the build failure of the Ada runtime on SPARC64/Linux, caused by a
miscompilation of the Ada front-end at -O2 or above. The symptom is exactly
the same as that of PR middle-end/44993, which was a similar build failure,
although the root cause is slightly different.
It's delicate stuff in the middle-end so I'm applying a trivial workaround to
the Ada front-end to unbreak the build and I'll create a testcase separately.
Boostrapped/regtested on SPARC64/Linux, applied on the mainline.
