OK, it turns out they use this to mean the parent of the package's source root, 
i.e. the directory that contains many packages' source code. This is what I was 
afraid some projects might use "source root" to mean (i.e. something like 
/usr/src), in the same way that $datarootdir in GNU conventions means 
/usr/share and $datadir refers to /usr/share/$pkg.

This is too long, I will just go with SOURCE_ROOT_DIR for the time being unless 
I get some better ideas. SOURCE_TOP_DIR is another candidate (used by 1 package 
as a python constant [1]) but I think both "top" and "root" suffers similarly 
from the ambiguity issue described previously.

On an unrelated note, I don't like this overuse of "I disagree" and it's a 
really bad pattern I've seen in various other internet threads. It's (1) a 
waste of readers' time (2) adds nothing to the discussion and (3) is 
pointlessly antagonistic. Indeed if 10 people replied to this thread merely to 
say "I disagree" I would completely disregard these replies; they don't push 
the discussion forward, nor explain why something is to be disagreed with. The 
statement is useless, let's focus on writing sentences actually related to the 
topic at hand.
