    gdb/testsuite: Allow DWARF assembler to create multiple line tables
    
    Fixes a bug in the DWARF assembler that prevents multiple line tables
    from being created in a test.  We currently don't initialise a couple
    of flags, as a result we will only ever generate one end of file list,
    and one end of header, in the first line table.  Any additional line
    tables will be missing these parts, and will therefore be corrupt.
    
    This fix will be required for a later commit.  There should be no
    change in the testsuite after this commit.
    
    gdb/testsuite/ChangeLog:
    
    	* lib/dwarf.exp (Dwarf::lines): Reset _line_saw_program and
    	_line_saw_file.
