Ah, right,
<http://git.savannah.gnu.org/gitweb/?p=dejagnu.git;a=commit;h=5256bd82343000c76bc0e48139003f90b6184347>...

However, that was not the problem here -- I'd been using such a DejaGnu
version.  That was strange, so I dug deeper, and found: in our *local*
DejaGnu board files a '[...]_target_compile' proc that likewise did need
to be fixed...  :-| With that done, the problem is then gone.

(I'm anyways attaching my "[WIP] nvptx: '-mdejagnu-ptx'", in case that's
ever useful for anyone, but not proposing to push that one.)

The "require a more recent version of DejaGnu" discussion never gets old,
eh...  ;-P
