# The BTARGET refers to objects that are derived from ldlinux.asm; we
# like to keep those uniform for debugging reasons; however, distributors
# want to recompile the installers (ITARGET).
#
# BOBJECTS and IOBJECTS are the same thing, except used for
# installation, so they include objects that may be in subdirectories
# with their own Makefiles.  Finally, there is a list of those
# directories.
