Subject: [PATCH] configure: don't enable ppc64abi32-linux-user by default
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The user can still enable this explicitly but they will get a warning
at the end of configure for their troubles. This also drops any builds
of ppc64abi32 from our CI tests.
