When you build world, you first spend a lot of time building a new 
toolchain using your systems' installed toolchain.  This new toolchain 
is what appears to be broken in the output you show.

So, you may well have a perfectly good toolchain installed, but a source 
tree that is defective -- mistakes do happen, and it can break building 
the world.

In this case, you can do the following to give yourself the best chance 
of building world successfully again:

    * delete everything under /usr/obj

    * check out the most recent sources using git or svn or svnlite or
      whatever you prefer

    * restart the build

Check the output from your buildworld and buildkernel for any errors and 
don't install unless the compile was error free.

Consider whether 13-CURRENT is the right version for you to run.  It is 
a development version and is not guaranteed to run correctly (or at 
all).  You're expected to be able to cope with such problems when you 
run it.  You will find -STABLE or -RELEASE a smoother ride and more 
performant to boot, as those code branches have certain performance 
impacting debugging code turned off.
