[gentoo-embedded] building klibc in an hardened environment

[Natanael Copa]

I am trying to build klibc in an hardened environment. The ssp causes
some problems. I wonder how I can turn off the ssp while compiling
klibc? I have tried USE="-hardened" CFLAGS="-fnostack-protector" but it
looks like the -fno-stackprotector option never is used. What can I do
to compile klibc in my hardened environment? Turning off SSP is ok. It
will only be used for initramfs anyway.

Here are som output:
