WITHOUT_GCC flag disables installation of /usr/bin/cpp too -- is it Ok?

[Lev Serebryakov]

Hello, freebsd-current.

  I'm building NanoBSD image based on latest HEAD sources. I've added
WITHOUT_GCC to install configuration, as I don't need gcc/g++ (it is
documented in man src.conf as disabling exactly gcc and g++), but it
affect /usr/bin/cpp too. And I need cpp for some config processing.

 Is it bug in documentation (man src.conf) or build system? I know
about WITHOUT_TOOLCHAIN, and it seems reasonable, that
WITHOUT_TOOLCHAIN disables cpp too, but not WITHOUT_GCC :(.
