* libgcj.spec.in: Use THREADSTARTFILESPEC to affect the spec for

	startfile.
	* configure.ac: Allow targets to affect the spec for startfile
	by specifying a THREADSTARTFILESPEC variable.  Define this for
	the win32 threads package to include crtmt.o.
	* configure: Regenerate.
	* win32.cc (_CRT_MT): Remove definition.
	(__mingwthr_key_dtor): Likewise.
