We've removed the special case code for upgrading from FreeBSD 9 so

remove the special warning. It's in svn if we need it.

****************************** SPECIAL WARNING: ******************************
Due to a bug in some versions of clang that's very hard to workaround in
the upgrade process, to upgrade to -current you must first upgrade
either stable/9 after r286035 or stable/10 after r286033 (including
10.3-RELEASE) or current after r286007 (including stable/11 and
11.0-RELEASE). These revisions post-date the 10.2 and 9.3 releases, so
you'll need to take the unusual step of upgrading to the tip of the
stable branch before moving to 11 or -current via a source upgrade.
stable/11 and 11.0-RELEASE have working newer compiler. This differs
from the historical situation where one could upgrade from anywhere on
the last couple of stable branches, so be careful.
If you're running a hybrid system on 9.x or 10.x with an updated clang
compiler or are using an supported external toolchain, the build system
will allow the upgrade. Otherwise it will print a reminder.
