(rtld-version-installed-name): New, default as ld-$(version).so. * Makefile (install): Call `$(common-objpfx)elf/ldconfig -d' only if $(cross-compiling) is no and $(build-shared) is yes. * Makerules (make-shlib-link): New macro. ($(slibdir)/libfoo.so.$(libfoo.so-version)): Use $(make-shlib-link) for symlink. (install-rootsbin, install-rootsbin-nosubdir): New.
