freebsd-dev/release/picobsd/build/Makefile.conf
Luigi Rizzo 3c560efb1a Provide a new picobsd option, "--modules", to also build modules
(modload and friends are sufficiently small to consider their inclusion
in PicoBSD images).

# Makefile for building PICOBSD kernels and running crunchgen
#
# Needs SRC pointing to the source tree,
# MY_TREE ponting to my tree
# BUILDDIR pointing to the build directory
# PICO_OBJ pointing to the object directory
# When building a kernel, also need ${name} from the environment
# and CONFIG may indicate an alternate config program

CONFIG?=config
MODULES?=-DNO_MODULES # do not build them as a default
# caller will set MODULES to empty if modules are needed.
# Indeed, it can be used to specify other Makefile options as well.
# These 3 variables determine where the kernel is built.
# If config were smart enough, we could place the config
# file in some other place than ${SRC}/sys/i386/conf, but
# at the moment (Oct.2001) this is not possible yet.
