[PATCH] Add support for rtld directory different from slib directory
Tested on aarch64 and x86.
Andreas.
* configure.in: Substitute libc_cv_slibdir.
* 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.
* sysdeps/gnu/configure.in: Set libc_cv_rtldir for s390x.
* sysdeps/gnu/configure: Regenerate.
ChangeLog.aarch64:
* sysdeps/unix/sysv/linux/aarch64/configure.in: Set
libc_cv_rtlddir.
* sysdeps/unix/sysv/linux/aarch64/configure: Regenerate.
