Upgrade gentoo
Upgrading to gentoo profile v17.1
Upgrading from:
[11] default/linux/amd64/17.0/no-multilib (stable) *
To:
[16] default/linux/amd64/17.1 (stable) *
There are a bunch of steps to follow in gentoo news... so... follow them! Set aside some time for this...
Upgrading to PHP 7
- edit /etc/portage/make.conf
# APACHE2_MODULES: update -D PHP5 to -D PHP # add php7-0 as target PHP_TARGETS="php5-6 php7-0"
- emerge everything
- use eselect to select it

I started down v17 so I better finish up. But let's go with the base profile (12). I used to use no-multilib (to avoid 32-bit support) but it sounds like there's little harm or cost in it.
Steps are described in eselect:

* Rebuild your entire system
emerge -e @world
Switching the profile from 13.0 to 17.0 modifies the settings of
GCC 6 to generate PIE executables by default; thus, you need to do
the rebuilds even if you have already used GCC 6 beforehand.
If you do not follow these steps you may get spurious build
failures when the linker tries unsuccessfully to combine non-PIE
and PIE code.
