ENDBR32 and RDSSPD are multi-byte NOPs on x86-64 processors and
newer x86 processors, starting Pentium Pro.  They are UD on older 32-bit
processors. Detect this at configure time and adjust the default value
for enable_cet. GCC will enable CET in 32-bit run-time libraries in any case
if --enable-cet is used to configure GCC.

OK for trunk?
