Description: Fix FTBFS (testsuite failure) on sparc64.
 Some tests crash with SIGBUS due to unaligned access.  The backtrace
 shows the culprit is CFTimeZoneCreate.c:171 where a pointer is
 dereferenced.  This is undefined behavior for all platforms that is
 just exhibited on sparc64 so let it apply to all architectures.
 .
 Skip a failing test which crashes with SIGSEGV in the PASS_CFEQ macro.
