Use newly built crt*.o files to build shared objects [BZ #22362]
When multi-lib GCC is used to build glibc, the search order of GCC driver for crt*.o is -B*/`gcc -print-multi-directory`, the installed diretory, -B*/. This patch adds multi-lib support to csu/Makefile so that -B/glibc-build-directory/csu/ will pick up the newly built crt*.o. Tested on x86-64 for i686 and x32. [BZ #22362] * Makerules (make-link-multidir): New. * config.make.in (multidir): New. * configure.ac (libc_cv_multidir): New. AC_SUBST. * configure: Regenerated. * csu/Makefile [$(multidir) != .](multilib-extra-objs): New. [$(multidir) != .](extra-objs): Add $(multilib-extra-objs). [$(multidir) != .]($(addprefix $(objpfx)$(multidir)/, $(install-lib))): New target.
