For final libc if you want to use fstack-protector-all   first build  
the libraries without that by adding build-programs=no in configrams,  
then directly build again with build-programs removed and add your  
CFLAGS for fstack-protector-all and whatever else.  That should work.  
Worked for Robert back in the day with his hardening builds!
