    Fix compilation errors with clang in gdb.base/advance.c
    
    Clang fails to compile the above file, with the following errors:
      warning: control reaches end of non-void function [-Wreturn-type]
      warning: too many arguments in call to 'func'
    
    This prevents the following testcases from executing:
      gdb.base/advance.exp
      gdb.base/until-nodebug.exp
    
    gdb/testsuite/ChangeLog:
    
            * gdb.base/advance.c (func): New argument, to match call site.
            (func2, func3): Add return statements.
