This works for me on both powerpc64-linux and a powerpc-darwin9 cross.

NOTE: I expect a reduced testsuite on powerpc-darwin since we build
"--with-libphobos-druntime-only" however, I am a bit surprised that
powerpc64-linux has roughly half the number of tests (590 c.f. 1100) of
x86_64-linux; is this expected? (independent of this fix, this was the case
before too).
