`make distclean' does not remove the subdir/.deps directories

[Alexandre Duret-Lutz]

... as a consequence `make distcheck' fails for all projects
using subdir sources.

I can see that lib/am/depend.am is outdated wrt to the recent
changes for pr224.  However the fix is not obvious to me.

The following change exhibits the problem.
