When I installed LFS-6.1, it was patched up to 2.6.17, one short. ;-( 
do this 6.6 install I patched to .18.  Grep didn't find STACKPROTECTOR
in my .config file.  I ran a menuconfig and looked in the "likely
places", but found no references to a stack protector option.  Only
found a few lines grepping the whole kernel branch for stack_protector.

If it were a hardware thing, wouldn't glibc's configure figure that out?

That failed at the same place.  This attempt wasn't able to override
its makefile parms, as shown here when it entered this directory.

As this is glibc, I'm not anxious to "get creative".  Don't know what to
do now.  Perhaps search kernel.org for more info?  The reference you
provided didn't initially look informative.  I'll look again, I guess.
