* sysdeps/unix/Makefile ($(common-objpfx)ioctls): Remove NULL from
the list. * time/northamerica: Corrections to Canada data from ADO 95i. * sysdeps/unix/sysv/linux/Makefile (headers): Don't append to this unconditionally. In socket subdir, append sys/socketcall.h; in time subdir, append sys/timex.h. (config-LDFLAGS): New variable. * sysdeps/unix/sysv/linux/Dist: New file. * Makeconfig (+link): Pass $(config-LDFLAGS) before $(LDFLAGS).
