From: Roland McGrath <roland@gnu.org>

Subject: * Makerules ($(common-objpfx)shlib.lds): New target.

	(common-generated): Add it.
	(build-shlib, build-module): Use that instead of generating every time.
	($(common-objpfx)libc.so): Depend on it.
	(lib%.so rule): Likewise.
	(build-module-helper-objlist): Remove %.lds.
	* iconvdata/extra-module.mk ($(objpfx)$(mod).so):
	Depend on $(common-objpfx)shlib.lds.
	* dlfcn/Makefile ($(test-modules)): Likewise.
