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.

Linus,
If you want to use this patch soon (seems useful since
you are travelling), please feel free to apply it directly.
If you wait for my next pull request, I will apply it to
my tree.
Either is fine with me.
