glibc/rtlddir.patch

From aaa8cb4b43511c62b11ac6f10e9beea3d5035a68 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/3] Add support for rtld directory different from slib
 directory

	* 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 $(rtld-installed-name).
	* elf/Makefile (install-others, CFLAGS-interp.c)
	(ldso_install, common-ldd-rewrite): Likewise.
	($(inst_rtlddir)/$(rtld-installed-name)): Renamed from
	$(inst_slibdir)/$(rtld-installed-name).
	* scripts/rellns-sh: Add -p option.
	* Makerules (make-shlib-link): Use rellns-sh to get relative name
	for source.
