2017-11-30  New 17.0 profiles in the Gentoo repository

If you are not already running a hardened setup with PIE enabled, then
switching the profile involves the following steps: 
If not already done,
* Use gcc-config to select gcc-6.4.0 or later as system compiler
* Re-source /etc/profile:
    . /etc/profile
* Re-emerge libtool
    emerge -1 sys-devel/libtool
Then, 
* Select the new profile with eselect
* Re-emerge, in this sequence, gcc, binutils, and glibc
    emerge -1 sys-devel/gcc:6.4.0
    emerge -1 sys-devel/binutils
    emerge -1 sys-libs/glibc
* Rebuild your entire system
    emerge -e @world
