This is now largely working.  The most obvious issues:

 - hivex had some endianness bugs which affected libguestfs, and
   libguestfs had a similar endianness bug:

 - libguestfs had a number of issues related to ppc:

 - PowerPC's larger page size (64K vs 4K) requires more appliance memory:

 - Btrfs is fairly broken, also seems to be related to larger page
   size.  I would suggest disabling it in libguestfs/ppc64 builds:

   libguestfs: error: btrfs_subvolume_create: /test1: ERROR: cannot create subvolume - No space left on device
   FAIL: test_btrfs_filesystem_sync_0
   libguestfs: error: btrfs_subvolume_create: /test1: ERROR: cannot create subvolume - No space left on device
   FAIL: test_btrfs_subvolume_delete_0
   libguestfs: error: mkfs_btrfs: /dev/sda1: Illegal leafsize (or nodesize) 4096 (smaller than 65536)
   FAIL: test_mkfs_btrfs_0
