interesting; somehow gcc does NOT put stack-protector in place despite it being
told so with -fstack-protector-all.

# -fno-common -funit-at-a-time -fstack-protector -fstack-protector-all
# -fno-asynchronous-unwind-tables -fno-omit-frame-pointer
# -fno-optimize-sibling-calls -fverbose-asm -fstack-protector
# -fstack-protector


this is weird; something is adding ANOTHER -fstack-protector to the (effective) gcc
flags.. which might be overriding the -fstack-protector-all setting.

I wonder if this is a distro special ;(
