Enable little endian Rijndael_UncheckedSetKey_POWER8 using built-ins
...
The problem was vec_sld is endian sensitive. The built-in required more than us setting up arguments to ensure the vsx load resulted in a big endian value. Thanks to Paul R on Stack Overflow for sharing the information that IBM did not provide. Also see http://stackoverflow.com/q/46341923/608639

Add CRYPTOPP_NO_CPU_FEATURE_PROBES (GH #511 )
...
We determine machine capabilities by performing an os/platform *query* first, like getauxv(). If the *query* fails, we move onto a cpu *probe*. The cpu *probe* tries to exeute an instruction and then catches a SIGILL on Linux or the exception EXCEPTION_ILLEGAL_INSTRUCTION on Windows. Some OSes fail to hangle a SIGILL gracefully, like Apple OSes. Apple machines corrupt memory and variables around the probe.
