* unix/configure.in: move check for fts API to configure.in and run it

	* unix/tcl.m4:       on all platforms, since Linux glibc2 and *BSDs also
	have this; using fts is more efficient than recursive opendir/readdir.
	* unix/tclUnixFCmd.c (TraverseUnixTree): add support to fts code for
	platforms with stat64.
	* unix/configure:
	* unix/tclConfig.h.in: regen.
