Aha. But you can add it for all linux:
/* { dg-additional-options "-mpowerpc64" { target powerpc*-*-linux* } } */
(or *-*-linux* even, everything in gcc.target/powerpc is known to be
powerpc*-*-* already).
Not that it matters at all here, as the other thread shows :-), but for
the future: run testcases wherever possible (and reasonable), and in the
same vein, try not to specialise option when you do not have to. Doing
this makes testing much less work, makes it easier to have reasonable
coverage.
