Not each _SOURCE file's, but in the same directory in which the object
will be put.  Which is the current builddir concatenated with the
dirname of each source file.

Does your setup actually build object files from the different packages
into the same subdirectory?  Maybe even same object files?  That would
sound dangerous to me.

Such things can often be avoided by rearranging the subdir structure a
bit.

Typically, that is a bad idea, esp. if the packages' rules for building
the object files get out of sync you have an implied race (a `cd subdir
&& make' will generate a different object from a plain make).

Hope that helps.
