--- Comment #1 from Siddhesh Poyarekar <siddhesh at sourceware dot org> ---
I can't reproduce this on my Fedora box using:

../configure CFLAGS="-march=nocona -mtune=native -O2 -pipe" --prefix=/usr
--disable-multiarch --enable-fortify-source

OR even

../configure CFLAGS="-march=nocona -mtune=native -O2 -pipe" CC="gcc -m32"
CXX="g++ -m32" --enable-stack-protector=strong --disable-cet
--enable-kernel=3.2.0 --without-selinux --disable-werror --enable-bind-now
--enable-fortify-source --build=i686-pc-linux-gnu --host=i686-pc-linux-gnu
--disable-profile --without-gd --with-headers=/usr/include --prefix=/usr
--disable-crypt --disable-multi-arch --disable-systemtap --disable-nscd
ac_cv_path_PERL=no libc_cv_aarch64_sve_asm=yes --disable-timezone-tools

Maybe the gentoo compiler driver is injecting something that I need to add to
this mix?

It should be '--disable-multi-arch'.

As I noted my proposed fix [1] only x86 is affected.  It is the only
architecture that tries to optimize the fortify wrapper with assembly routines.
