Seems to.

Intending to attempt to duplicate __stack_chk_guard error in chapter 6
while building lfs-6.6 from lfs-6.1.1 ...
The theory being that the host gcc/glibc "ideal" gets passed to the
toolchain build and then passed to the finished build as if it were an
olympic torch.

I'm using the exemplary jhalfs.
lfs-6.2 original host (hostname lfs)
lfs-6.1.1 target partition /dev/sdb8 (hostname lfs-1)
lfs-6.6 target partition /dev/sdb9

Stage 1 - build lfs-6.1.1
-------------------------
me at lfs:~/jhalfs-0.2$
su # stay in root for this version
mount /dev/sdb8 /mnt/lfs
./jhalfs -L 6.1.1
cd /mnt/lfs/jhalfs
make
... it goes on for hours and then is done.
... chroot into it and build a requisite kernel.
... shutdown and boot to it (entertaining grub in the process).

Stage 2 - build lfs-6-6
-----------------------
me at lfs-1:~/jhalfs-2.3.2$
su
mount /dev/sdb9 /mnt/lfs
exit # to regular user for this version
make
.... select the options and approve
cd /mnt/lfs/jhalfs
make BREAKPOINT=038-gcc-pass2

... while that is building, I see in gcc-build/config.log
"Reading specs from ...  Configured with: ... --disable-libssp"
... I decide to break out of it, and try something

I imagine this will be ok.

Fun!
