Er... of course this won't work. The .c file isn't in $(objdir), so it
will never match the pattern $(objdir)/%.c.
You have to use the source directories in the pattern for the .c files.
The idea is to use a prefix that is "above" the source directories. As
I said above, depending on your environment this might be difficult or
even impossible.
Given the constraints I have already given then, it looks like this is
impossible. I have no clue what the prefix would be because the files
come from a variable set by the owner of a particular directory in the
tree and can point anywhere (including outside of the tree).
I'll go back to evaluating replacing make with scons, now.
