Not about llvm/clang.

Including /etc/src.conf has problem of conflicting world knob and
port knob.
Skipping to include /etc/src.conf by <bsd.own.mk> is needed.
It's difficult for base system.
Then <bsd.port.mk> define _WITHOUT_SRCCONF and skip
including /etc/src.conf.

But some ports include <bsd.*.mk> (exclude <bsd.port*.mk>)
has bug, because they don't define _WITHOUT_SRCCONF.

NOT bool, the variable is defined or not.
The options are written in /etc/make.conf
