+ * configure.in: Substitute libc_cv_rtlddir.
+ * configure: Regenerate.
+ * config.make.in (rtlddir): Set from libc_cv_rtlddir.
+ * Makeconfig (rtlddir, inst_rtlddir): New variables.
+ (rtld-LDFLAGS): Use them with $(rtld-installed-name).
+ * elf/Makefile (install-others, CFLAGS-interp.c)

+ $(inst_slibdir)/$(rtld-installed-name).
+ * scripts/rellns-sh: Add -p option.
+ * Makerules (make-shlib-link): Use rellns-sh to get relative name
+ for source.
