freebsd-nq/sys/conf/Makefile.i386
Sheldon Hearn f66116083c When building a debugging kernel with modules, build modules with
debugging support as well.  Debugging module support is handled
identically to kernel debugging support, right down to poor
choice of make variable names.

# Generic makefile changes should be made in
# /sys/i386/conf/Makefile.i386
# after which config should be rerun for all machines.

# Which version of config(8) is required.
