* Makefile (multidir): Don't set the variable here with $(shell ...). ($(objpfx)multidir.mk): New target, generated makefile; include that. (generated): Append it. 2003-04-10 Jakub Jelinek <jakub@redhat.com> * Makefile (multidir, crti-objs, crtn-objs): New variables. (generated-dirs): Add pathname component of multidir. (omit-deps, extra-objs): Include $(multidir)/crt? as well. ($(objpfx)libpthread.so): Depend on $(multidir)/crt?.o as well. ($(objpfx)$(multidir), $(objpfx)$(multidir)/crti.o, $(objpfx)$(multidir)/crtn.o): New. * sysdeps/unix/sysv/linux/sparc/Makefile: Removed. * sysdeps/unix/sysv/linux/x86_64/Makefile (LDFLAGS-pthread.so, before-compile, generated): Don't generate and use specs. ($(objpfx)specs): Remove.
