most probably, at least one of your object files/libraries has been compiled with the -fpic option. You have to fix that, overriding the flag with flthdr doesn't work. Do you have a special reason why you want to build busybox without xip? You know that the large text segment of busybox is allocated seperately for each instance of busybox that you are running?
