Shortly, there was a discussion about a fully installed LLVM/CLANG and
the portion of LLVM/CLANG, that is only needed to compile the system's
source. In this case, a strict separartion was intended.

This implies w have setting only applicable for the core system and we
deal with settings for various ports.

I though, until now, FreeBSD, as other *BSDs, follow a strict logical
policy and this implies, in my opinion, that there is in strictu sensu a
separation between the sources of the core system and those for the ports.

If the manpage of /etc/src.conf says that only bool knobs are allowed
like WITH_XXX or WITHOUT_XXX, then: where to put the options?

I feel confused by having /etc/src.conf also involved in port's
compilations and in my opinion, this is a bug! It torpedos the logic
described in the manpage with sounds reasonable to me (the manpage of
src.conf).

If the build system really needs to intertwine both make.conf and
src.conf for ports, then something is illconditioned.
