Subject: [PATCH] kbuild: Fix unnecessary rebuilding DT base+overlay targets

Commit 5d0cac427d42 ("kbuild: Support directory targets for building
DTBs") causes base+overlay targets to be rebuilt every time. The problem
is due to the added check on $(MAKECMDGOALS) which now testing again
doesn't even seem to be needed. Revert that portion of the commit.
