This does not happen on a powerpc-linux build. Sorry, I had misdiagnosed, at the time of the report, the reason for -mpowerpc64 to be enabled; I later found out it was just the presence of a powerpc64-enabled -mdejagnu-cpu in the testcase that enabled it, the default cpu for ppc-elf doesn't enable it. (Nevertheless, many other tests needed -mno-powerpc64 to get the expected ilp32 results on ppc-elf, also because of -mdejagnu-cpu options; patch to be submitted shortly).
