* unix/Makefile.in: add support for compile flags specific to

				object files linked directly into executables.

	* unix/configure.in (Darwin): only use -seg1addr flag when prebinding;
	use -mdynamic-no-pic flag for object files linked directly into exes;
	support overriding TCL_PACKAGE_PATH/TCL_MODULE_PATH in environment.

	* unix/configure: autoconf-2.59
