Igor Tsimbalist 14e335edc8 CET shouldn't be enabled in 32-bit run-time libraries by defualt 
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.

	PR target/84148
	* config/cet.m4: Check if target support multi-byte NOPS (SSE).
	* libatomic/configure: Regenerate.
	* libbacktrace/configure: Likewise.
