* csu/Makefile [$(elf)=yes] (have-initfini): Set to yes.

	[$(have-initfini)=yes]: Test this rather than $(elf) for crtstuff.
	[start-installed-name-rule]: If this is defined, elide rule for
	$(objpfx)$(start-installed-name).
	* sysdeps/unix/sysv/sco3.2.4/Makefile [$(subdir)=csu]
 	(start-installed-rule, start-installed-name-rule): New variables;
 	specify crt1.o, created by our own rule.
	($(objpfx)crt1.o): New rule.
	* configure.in: Require autoconf 2.4.2 or later.  Change all
 	AC_CACHE_VAL uses to use new AC_CACHE_CHECK macro instead;
 	prettify some messages.
	[$elf!=yes] (libc_cv_have_initfini): New test for `.init' and `.fini'
	sections.
	* munch-tmpl.c [HAVE_INITFINI]: Call _init and atexit (_fini) in
 	this case rather than #ifdef HAVE_ELF.
	* config.h.in (HAVE_INITFINI): New macro.
