If you're asking what I think (you want to add code of your own into
the buildworld), just add LOCAL_DIRS="path/to/dir1 path/to/dir2" to the
buildworld command line and it will visit your directories and run the
same targets there as for standard freebsd dirs (so your makefiles have
to have those targets, mostly easily accomplished by including the
usual bsd.<foo>.mk where foo=prog|lib|subdir|whatever.

The local dir paths in LOCAL_DIRS must be relative to the top-level
freebsd source dir, you can't use absolute paths (but you can use
relative paths that take you outside the freebsd path, I think, like
../mysources/project1).
