When it then reads an item from there as something not a multiple of 4

rs6000: Fix the new SSP guard configuration code (PR79140)

I foolishly tested this with r241087 reverted.  After that revision
default_stack_protect_guard is no longer called if the compiler defaults
to using the TLS guard, which of course is the wrong thing to do if
there is some other way to enable the global guard.
