* 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.
