I do buildworld/buildkernel on a powerpc64 targeting itself via
lang/powerpc64-xtoolchain-gcc (a.k.a. lang/powerpc64-gcc for the most part).
[Getting that lang/powerpc64-gcc installed for self-hosted use does take some
work-around activity.] I have buildworld build clang (but not use it). [I've
been doing this with 11.0-CURRENT for a long time.]
Actually I use lang/gcc49 as the "system compiler" and lang/powerpc64-gcc as
the self-hosting so-called "cross compiler". (I later list the src.conf
content.) gcc4.2.1 is not installed.
Trying to go from:

I'll not list it all: There is a lot.
