In the building niggas building like little children, staring
Them older niggas ain't caring

from Raekwon (Ft. Ghostface Killah & Nas) – Verbal Intercourse Lyrics on Rap Genius

The homograph Building is a five percent Nation of Gods and Earths term for discussing information and educating each other as it deals with their world view.
And it refers to the building in their hood

the simile of children staring is the apathy of the older folks who aren’t involved and are content with the status quo
