Because sim/moxie/moxie-gdb.dtb is neither a program nor a library, automake does not generate dirstamp file ($builddir/sim/moxie/.dirstamp) for it. When maintainer mode is enabled, it tries to rebuild sim/moxie/moxie-gdb.dtb but fails because there's no rules for automake-generated dirstamp file which moxie-gdb.dtb depends. This commit adds its own rule for the directory stamp (modified copy of the automake output) and adds the directory stamp file to DISTCLEANFILES to mimic automake-generated behavior (although "make distclean" does not work when maintainer mode is enabled).
