[gentoo-embedded] uclibc don't compile with USE="hardened"

[Natanael Copa]

I run this:
ucgentoo:/ # ROOT=/usr/src/alpine/live/ CFLAGS="-Os -march=i386" USE="hardened" emerge  uclibc

Here is the last of the output:

It compiled without hardened in USE flags and with
CFLAGS="-fstack-protector" but I haven't checked if it really was
compiled with -fstack-protector. (How do I do that?)
