Bug 1261531 - Remove most obvious cases of useless AC_DEFINEs. r=chmanchester - HW_THREADS doesn't appear to be doing anything. - USE_ARM_KUSER is not used since bug 675078. This also removes the configure flag that sets it. - HAVE_SETBUF and HAVE_SNPRINTF are leftover from bug 944935. - MOZ_MEMORY_GONK is leftover from bug 804303.
