#     kbuild: make multiple directory targets work
#     
#     Currently, the single-target build does not work when two
#     or more sub-directories are given:
#     
#       $ make fs/ kernel/ lib/
#         CALL    scripts/checksyscalls.sh
#         CALL    scripts/atomic/check-atomics.sh
#         DESCEND  objtool
#       make[2]: Nothing to be done for 'kernel/'.
#       make[2]: Nothing to be done for 'fs/'.
#       make[2]: Nothing to be done for 'lib/'.
#     
#     Make it work properly.
