[ Upstream commit f566e1fbadb686e28f1c307e356114b2865ef588 ]
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.
