* Makeconfig ($(common-objpfx)config.status):
	Fix typo: $(add_ons) -> $(add-ons).
	(Makeconfig-add-on): New variable.  When doing $(sysdep-makeconfigs)
	include, use black magic to get it set to an add-on's name during the
	include of the add-on's Makeconfig.

	* configure.in: Use variable name `libc_add_on' when sourcing add-on
	configure fragments, so they can refer to this.
	* configure: Regenerated.
