base/binutils (from ports/head -r424540) requires "gcc" to be a valid command on the host environment

clang and clang++ 3.8.0 do not work correctly for powerpc64 or powerpc for
FreeBSD: various forms of bad code generation and ABI violations. No version
works yet as far as I know. (There has been some recent work on this in llvm
but some of it has not been put in the FreeBSD clang/clang++ 3.9.0 experiment
so far.)

(I sometimes experiment with clang/clang++ on powerpc and analyze the problems
and submit reports of the ones that I find.)

powerpc64 and powerpc also do not have prebuilt packages, not even just one
for pkg itself.

This makes getting both a C/C++ compiler set and pkg in place a bit of a mess
even for a cross-built bootstrap:

A) pkg on the target needs to be built by a C/C++ compiler toolchain.

B) /usr/ports/base/gcc usage for getting a compiler toolchain on the target
   works by putting a .txz file in place for use via pkg add <THAT-FILE> .
