Enabling DEBUG= in rom-o-matic is a great idea.  People often want to
see the debug output but prefer not to build from source.

I think we should drop the limited set of pre-defined DEBUG= options
and allow the raw DEBUG= list to be specified.  This gives access to
every debuggable object file and the debug level can be set too (e.g.
scsi:3 enables DBG + DBG2).

The syntax for DEBUG= is:
obj_1[:lvl][,obj_2[:lvl]]*

The object file name should be letters, digits, underscore, and
hyphen.  The debug level is an integer.  There may be one or more
object files listed, separated by a comma.
