Roland McGrath 8e3cc80f6d Tue Oct 10 23:08:53 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu>
* Makerules (build-shlib): Pass -rpath and -rpath-link options.
	(LDFLAGS-c.so): Don't pass -dynamic-linker here.
	* Makeconfig (+link): Pass $(sysdep-LDFLAGS).
	(link-libc): Pass -rpath and -rpath-link options.

	* MakeTAGS (all-dirs): Omit CVS directories.
	Specify vpath directives to find source files in $(all-dirs).
	(sources, headers): Append sources and headers from $(all-dist) to
	these. 
	(all-dist): Filter them out of this.
	(all-headers, all-sources): Use $(shell find ...) instead of
	$(wildcard ...).

	* sysdeps/mach/hurd/Makefile (sysdep-LDFLAGS): New variable; pass
	-rpath-link.

	* hurd/hurdexec.c: Pass poly and dealloc args to __file_exec.

	* elf/Makefile (install-others): Add missing $.

	* mach/Makefile ($(objpfx)errsystems.c): Rule reenabled.
