* unix/Makefile.in, unix/tcl.m4: move (C|LD)FLAGS after their

	* unix/configure.in, unix/configure: _DEFAULT to allow for env
	setting to override m4 switches.
	Consolidate header checks to limit redundancy in configure.
	(CFLAGS_WARNING): Remove -Wconversion, add -fno-strict-aliasing
	for gcc builds (need to suppress 3.x type puning warnings).
	(SC_ENABLE_THREADS): Set m4 to force threaded build when built
	against a threaded Tcl core.
	Reorder configure.in for better 64-bit build configuration,
	replacing EXTRA_CFLAGS with CFLAGS.  [Bug #874058]
