I'd suggest you first do a clean gcc upgrade to gcc-6.4.0 or gcc-7.2.0
depending on whether you run a stable or a testing system.
https://wiki.gentoo.org/wiki/Upgrading_GCC
And then follow exactly the steps in the news item after the step of
rebuilding gcc.
Or in detail:
Run these commands:
# gcc-config -l
# gcc-config set <number of the latest gcc profile>
# emerge -1 sys-devel/gcc
# gcc-config -l
# gcc-config set <number of the latest gcc profile>
# source /etc/profile
# emerge -1 sys-devel/libtool
# gcc --version
# emerge --depclean =sys-devel/gcc-<versionnumber> [for all installed
gcc versions except for the latest (6.4.0 or 7.2.0)]
# emerge -1 sys-devel/binutils
# emerge -1 sys-libs/glibc
# emerge -e @world
