#   The global lint target builds the kernel lint library (llib-lunix.ln)
#   which is equivalent to a lint of /unix.o. Then all kernel modules for
#   this architecture are linted against the kernel lint library.
#
#   Note:   lint errors in the kernel lint library will be repeated for
#       each module. It is important that the kernel lint library
#       be clean to keep the textual output to a reasonable level.
