# $FreeBSD$
# Part of a unified Makefile for building kernels. This part contains all
# of the definitions that need to be before %BEFORE_DEPEND.
# Allow user to configure things that only effect src tree builds.
# Note: This is duplicated from src.sys.mk to ensure that we include
# /etc/src.conf when building the kernel. Kernels can be built without
# the rest of /usr/src, but they still always process SRCCONF even though
# the normal mechanisms to prevent that (compiling out of tree) won't
# work. To ensure they do work, we have to duplicate thee few lines here.
