[Pdbg] [PATCH] Makefile.am: Fix dependencies for specific .dtb.o files

dtc supports the `-d` option:

  -d, --out-dependency <arg> 
        Output dependency file

If we were going to do this properly we'd just teach make how to generate the
dependencies automatically. In the meantime I agree - removing the dependencies
doesn't seem right. Cyril does Joel's patch above fix the issue you were seeing?

Alistair
