[OE-core] [PATCH] boost: properly fix do_boostconfig re-execution

[Martin Jansa]

* it was partially fixed in:
  commit 291e20a51544c640d07767d1dc32d762f4370f41
  Author: Venkata ramana gollamudi <ramana.gollamudi at huawei.com>
  Date:   Fri Apr 13 11:42:46 2012 +0000
  Subject: boost: fix re-execution of task

  but with disadvantage that when CXX or *FLAGS variables were changed
  it was continuing to use old values
* just remove the line before appending it with current values to fix
  that
