re PR libstdc++/36924 (mt_allocator/deallocate_local_thread-5.cc and ext/mt_allocator/deallocate_local_thread-7.cc fail sometimes)

2008-07-24  Paolo Carlini  <paolo.carlini@oracle.com>

      	PR libstdc++/36924
      	Revert:
      	2008-07-23  Chris Fairles <chris.fairles@gmail.com>

      	* acinclude.m4 ([GLIBCXX_CHECK_CLOCK_GETTIME]): Define GLIBCXX_LIBS.
      	Holds the lib that defines clock_gettime (-lrt or -lposix4).
      	* src/Makefile.am: Use it.
      	* configure: Regenerate.
      	* configure.in: Likewise.
      	* Makefile.in: Likewise.
      	* src/Makefile.in: Likewise.
      	* libsup++/Makefile.in: Likewise.
      	* po/Makefile.in: Likewise.
      	* doc/Makefile.in: Likewise.
