2017-11-30-new-17-profiles: Display based on profile, not gcc version

Display the news item on 17.0 profile upgrade to all users using 13.0
profiles, rather than the people having new enough gcc installed. Given
that all users see the new profile, it is not a good idea to show
the news item to subset of them and leave the rest without any
instructions. Furthermore, displaying the item to users using 17.0
already is usually pointless.

+Title: New 17.0 profiles in the Gentoo repository
+Author: Andreas K. Hüttel <dilfridge@gentoo.org>
+Posted: 2017-11-30
+Revision: 1
+News-Item-Format: 2.0
+Display-If-Installed: >=sys-devel/gcc-6.4.0
+
+We have just added (for all arches except arm and mips, these follow
+later) a new set of profiles with release version 17.0 to the Gentoo 
+repository. These bring three changes:
+1) The default C++ language version for applications is now C++14.
+   This change is mostly relevant to Gentoo developers. It also
+   means, however, that compilers earlier than GCC 6 are masked 
+   and not supported for use as a system compiler anymore. Feel 
+   free to unmask them if you need them for specific applications.
+2) Where supported, GCC will now build position-independent
+   executables (PIE) by default. This improves the overall
+   security fingerprint. The switch from non-PIE to PIE binaries,
+   however, requires some steps by users, as detailed below.
+3) Up to now, hardened profiles were separate from the default
+   profile tree. Now they are moving into the 17.0 profile
+   as a feature there, similar to "no-multilib" and "systemd".
+
+Please migrate away from the 13.0 profiles within the six weeks after
+GCC 6.4.0 has been stabilized on your architecture. The 13.0 profiles
+will be deprecated then and removed in half a year.
+
+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
+
+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.
