#     kbuild: make single target builds even faster
#     
#     Commit 2dffd23f81a3 ("kbuild: make single target builds much faster")
#     made the situation much better.
#     
#     To improve it even more, apply the similar idea to the top Makefile.
#     Trim unrelated directories from build-dirs.
#     
#     The single build code must be moved above the 'descend' target.
