[build] Fix DEBUG builds for filenames with hyphens

Browse Source 
Debug builds for filenames with hyphens such as:

     $ make bin/via-rhine.dsk DEBUG=via-rhine

fail with:

     [BUILD] bin/via-rhine.dbg1.o
     <command-line>: error: missing whitespace after the macro name
     make: *** [bin/via-rhine.dbg1.o] Error 1

This is because "-" is not a legal character in C identifiers, and
gcc rejects "-Ddebug_via-rhine=1" as an argument.
