The problem appears to be that you use the "-MM" flag of gcc, which
recursively finds all dependencies.  But you specify a "depend" action
without the "recursive" flag.  I don't think you can tell gcc to do this
non-recursively.

You could add the "{recursive}" argument to the "depend" action, perhaps
that already solves the problem.  Otherwise you can use the default
depend action without using gcc.  This requires a recent Aap version
that supports the HASGCC variable.  Set HASGCC to "no".

I now wonder if the internal dependency function checks the "autodepend"
attribute.

I don't see a simple way to make a "depend" action that is not
recursive, so that at each level the "autodepend" attribute can be
checked and files skipped where it's off.  This would require using
Python to do your own dependency checking.
