Commit 5c4e74c68c3262ee35bd039d94b0237df7381888 (profiles: Use latest vim for
cross compile fix) updated vim to vim-7.4.712, which outdates this local fix.

Missed this reference to /usr/local/portage in a recent scripts change:
174a847e36
So existing SDKs kept working but newly created SDKs would mysteriously
fail to build some things like cmake and vim. :(
Specify vim-7.4.712 and vim-core-7.4.712 in package.accept_keywords
to pickup needed upstream cross-compile fix.

Fix build errors like these:
checking for tgetent()... configure: error: NOT FOUND!
You need to install a terminal library; for example ncurses.

This now includes ignition-disks.service and ignition-files.service
which run their respective stages. Both of these services are required
by ignition.target which is wanted when the udev rule matches an
unbooted disk.
In addition to enabling PIE and stack protector, hardened compilers also
enable the -fstack-check option which I had previously overlooked,
conflating it with -fstack-protector which the kernel build already
handles properly. This is the second time I hit this trying to use
ccache, I forgot that -nopie was insufficent for kernel builds. Last
time around reverted in cd043688f09b22ccf245ffd11f8a22a5ff31e577.
At least this time I finally dug deep enough to find the cause instead
of setting myself up for repeating history in another 6 months. For
reference the issue is that the Go 1.3.x runtime can call clock_gettime
with a very small stack. If the vDSO library was built with
-fstack-check it will attempt to write 0 to a location beyond the end of
the very small stack, triggering SEGV:
