This includes new source tarballs, updated patches, and updated
expected results for test cases.  In addition, three new tables
(PRMT, RGRT and SVKL) now have big-endian support.

Subject: [PATCH 04/45] Re-enable support for big-endian machines
First, disable the big-endian check and fail. Then, make sure the
namespace gets initialized properly (NB: needed even if we are only
compiling/disassembling data tables).
