[OE-core] [PATCH 2/2] gcc-source.inc: fix STAMPCLEAN to avoid race issue

[Robert Yang]

Fixed race issue when build more than one gcc-source and inherit
rm_work, for example:
$ bitbake gcc-source-4.9.2 gcc-source-5.1.0

File "/path/to/bitbake/lib/bb/build.py", line 512, in exec_task
  return _exec_task(fn, task, d, quieterr)
File "/path/to/bitbake/lib/bb/build.py", line 489, in _exec_task
  make_stamp(task, localdata)
File "/path/to/bitbake/lib/bb/build.py", line 599, in make_stamp
  os.unlink(name)
OSError: [Errno 2] No such file or directory: '/path/to/tmp/stamps/work-shared/gcc-4.9.2-r0.do_rm_work_all.02cf1ed9b79d4edb0a51d3b913b7f9ba'

This is because make_stamp() uses glob.glob() to remove the old stamps
before create the new one, when gcc-source-5.1.0 removes gcc-4.9.2-r0's
stamp, we may get the error.

We can't use deltask do_rm_work_all as do_rm_work since it is a
recrdeptask, otherwise:
ERROR: Command execution failed: Traceback (most recent call last):

    commandmethod(self.cmds_async, self, options)
  File "/path/to/bitbake/lib/bb/command.py", line 324, in generateDotGraph
    command.cooker.generateDotGraphFiles(pkgs_to_build, task)
  File "/path/to/bitbake/lib/bb/cooker.py", line 847, in generateDotGraphFiles
    depgraph = self.generateTaskDepTreeData(pkgs_to_build, task)
  File "/path/to/bitbake/lib/bb/cooker.py", line 672, in generateTaskDepTreeData
    rq.rqdata.prepare()
  File "/path/to/bitbake/lib/bb/runqueue.py", line 587, in prepare
    generate_recdeps(dep)
  File "/path/to/bitbake/lib/bb/runqueue.py", line 575, in generate_recdeps
    add_resolved_dependencies([taskData.tasks_fnid[t]], tasknames, newdeps)
TypeError: list indices must be integers, not NoneType

Update STAMPCLEAN to contain ${PV} to fix the problem.
