Similarly to what was done for the regular character, fortified printing functions, this patch combines the mode masks PRINTF_LDBL_USES_FLOAT128 and PRINTF_FORTIFY to provide wide character versions of fortified printf functions. It also adds two flavors of test cases: one that explicitly calls the fortified functions, and another that reuses the non-fortified test, but defining _FORTIFY_SOURCE as 2. The first guarantees that the implementations are actually being tested (independently of what's in bits/wchar2.h), whereas the second guarantees that the redirections calls the correct function in the IBM and IEEE long double cases. Tested for powerpc64le. Reviewed-By: Paul E. Murphy <murphyp@linux.ibm.com>
