If they are installed, make sure they are not active, then uninstall them.

One may can add the -t option and see what is pulling it in.  That may,
or may not, lead to a clue.

There are two things which emerge can tell you with this message.

1. It can't find >=sys-devel/gcc-6.4.0 but only older gcc versions.

2. You have installed a package that depend on sys-devel/gcc-5.4.0-r3
or sys-devel/gcc-4.9.4.

I already explained what you can do in the first case. In the second
case I would try to fix (uninstall, rebuild, upgrade or whatever) those
packages which depend on an outdated gcc. I guess equery is your friend.

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 
# emerge -1 sys-devel/gcc
# gcc-config -l
# gcc-config set 
# source /etc/profile
# emerge -1 sys-devel/libtool
# gcc --version
# emerge --depclean =sys-devel/gcc- [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
