    [gdb] Ignore trailing whitespace in gdb/gdb-gdb.gdb.in
    
    In gdb/gdb-gdb.gdb.in we have:
    ...
    gdb/gdb-gdb.gdb.in:22: trailing whitespace.
    +set prompt (top-gdb)
    ...
    
    The trailing space is significant.
    
    Fix this by dropping the trailing whitespace check for this file.
